Signature of Plausible Accreting Supermassive Black Holes in Mrk 261 / 262 and Mrk 266

We address the neutrino radiation of plausible accreting supermassive black holes closely linking to the 5 nuclear components of galaxy samples of Mrk 261/262 and Mrk 266. We predict a time delay before neutrino emission of the same scale as the age of the Universe. The ultrahigh energy neutrinos are produced in superdense protomatter medium via simple (quark or pionic reactions) or modified URCA processes (G. Gamow was inspired to name the process URCA after the name of a casino in Rio de Janeiro). The resulting neutrino fluxes for quark reactions are ranging from J ]ε/(εd erg cm −2 s sr) ≃ 1.1×10 to 8.2×10, where ε d ∼ 10 −12 is the opening parameter. For pionic andmodified URCA reactions, the fluxes are J ]ε ≃ 0.1J q ]ε and J URCA ]ε ≃ 7.4×10 −11 J q ]ε, respectively. These fluxes are highly beamed along the plane of accretion disk, peaked at ultrahigh energies, and collimated in smaller opening angle θ ∼ ε d .


Introduction
The interactions between galaxies may promote key processes in galaxy evolution including mass assembly, star formation, morphological transformation, and activity of AGNs.Among various proposals is the hierarchical galaxy formation hypothesis, wherein the galaxies and galactic structures are formed through merging of smaller galaxies/structures.The galaxy-galaxy interactions/mergers, as well known, can significantly enhance the star formation rate in the respective galaxies; see, for example, [1] for a review.Each proposal towards galaxy-galaxy interactions/mergers has its own advantage and limitations in proving the whole view of the issue.If tidal plume and tails indicative of classical merger remnants can be seen, it seems reasonable to accept the merging hypothesis, as in the case of many Markarian galaxies with a binary nucleus.However, some Markarian galaxies with multiple nuclei do not show any sign of tidal effects.If obvious tidal features are not easily detectable, it is wise to place constraints on the likelihood of the merger hypothesis as it was done in the pioneering discussions of Ambartsumian in the 1950's and 1960's for analyzing the observational data of eruptive activity of galactic nuclei and energetic nonstationary phenomena in the Universe [2][3][4].Recently, we present a spectroscopic investigation [5] of the galaxy samples of Mrk 261/262 and Mrk 266.The nuclear components in both of these samples show quite similar emission lines in their spectra.Besides, they do not show any sign of tidal effects.Therefore, one cannot exclude the alternative possibility that galactic nuclei in these samples, for example, may separate by fission rather than merging.A useful framework for such viewpoint is the microscopic theory of black hole (MTBH), originally proposed by [6] (see references therein), and further discussed by [7].Therefore, our interest is to apply the predictions of MTBH to observational data of unique galaxy samples of Mrk 261/262 and Mrk 266 as a backdrop to validate the microscopic approach with some observational tests.The MTBH supports the idea of accreting supermassive black holes linked to AGNs and their neutrino radiation.With this perspective in sight, we address the essential features of 5 nuclear components in Mrk 261/262 and Mrk 266.Certainly, it would be proper also to compare the prediction on neutrino emission from the large number of AGN black holes, well known from the literature.This will be done elsewhere.
Advances in Astronomy 1.1.Motivation.We have put forward the microscopic theory of black hole as a possible way to innovate the solution to the key problem of the AGN powerhouse.Recall that ever since the discovery of the rapid release of large amounts of energy from galactic nuclei and the origin of compact objects, the main problem has been to identify the physical mechanisms behind these phenomena.A major unsolved problem is how efficiently such huge energies observed can be generated.This energy scale severely challenges the conventional source models.The longstanding standard phenomenological black hole model (PBHM) cannot successfully support such investigations, because the theory breaks down inside the event horizon, whereas the meaningless singularity develops at the center inside of the stationary black hole, which is causally disconnected from the exterior world.The ultimate fate of the collapsing matter once it has crossed the black hole surface is unknown.So, the central singularity does not allow a further mass assembly.In the framework of PBHM, neither a growth of black hole mass promoted by accretion process nor an increase of energy density occur.Therefore, the required huge energy scale to account for the resulting activity of galactic nuclei cannot be reached.On the other hand, a complex study of AGN evolution requires a comprehensive understanding of the important phenomenon of the black hole growth.This idea gathers support from a breakthrough made in recent observational, theoretical, and computational efforts on understanding of coevolution of black holes and their host galaxies, particularly through self-regulated growth and feedback from accretion-powered outflows; see, for example, [8][9][10][11][12][13][14].Thus, the PBHM cannot be currently accepted as the convincing model for addressing the aforementioned problems.To fill the void which the standard PBHM presents, one possible way to improve this situation is the microscopic theory of black hole.The MTBH is the extension of the PBHM, which rather completes PBHM by exploring the most important processes of rearrangement of vacuum state and a spontaneous breaking of gauge symmetry in gravity at huge energies (see [6,15,16]).Thereby, a discussed gravitational theory is consistent with the general relativity up to the limit of neutron stars.Namely, the observational values are in a variety of ways well within the range of theoretically allowed masses of neutron star models discussed here.But MTBH also manifests its virtues applied to the physics of internal structure of galactic nuclei.A significant change of properties of space-time continuum, so-called inner distortion (ID), arises simultaneously with the strong gravity.This causes the matter to undergo a phase transition of second kind, which supply a powerful pathway to form a stable superdense protomatter core (SPC) [6,7] (see Appendix A.1 of present paper).The crucial difference from PMBH is that the central singularity cannot occur now.Instead, this is replaced by finite though unbelievably extreme conditions.The SPC accommodates the highest energy scale up to hundreds ZeV in protomatter core to account for the spectral distribution of the resulting radiation of galactic nuclei.External physics of accretion onto black hole in the earlier part of its lifetime has tight links to the processes in Schwarzschild's model.However, an essential difference in the model context between a true black hole and the SPC arises in the later part of its lifetime [7].The SPC surrounded by the accretion disk presents the microscopic model of AGN (Appendix A.1).The seed black hole might grow up driven by the accretion when it was getting most of its mass.That is, with time an infalling matter forms protomatter disk around protomatter core tapering off faster at reaching out the thin edge of event horizon.At this, metric singularity inevitably disappears and the neutrinos may escape through opened vista to the outside world.We will not be concerned here with the actual details of MTBH.The interested reader is invited to consult the original papers for further details.

Expected Results.
Our computations in the present paper are partially based on [7], which has dealt with the preradiation time (PRT) of neutrinos from AGN black holes with well-determined masses and bolometric luminosities, collected from the literature [17].The PRT is referred to as the earlier part of the lifetime  BH of black hole from its birth till neutrino radiation.For the latter part of the lifetime,  >  BH , the black hole no longer holds as a region of space time that cannot communicate with the external Universe (see Appendix A.1).The ultrahigh energy (UHE) neutrinos are produced in superdense protomatter medium of SPC via simple (quark or pionic reactions) or modified URCA processes.Consequently, the neutrinos may escape through opened vista to outside world even after the neutrino trapping.We estimate the  BH masses and bolometric luminosities  bol in order to compute the PRTs and neutrino fluxes for the Mrk 261/262 and Mrk 266.These galaxy samples can be served as pure UHE neutrino sources.Note that the point-like sources of neutrinos are the most essential ingredients of Z-burst scenario [18][19][20][21][22][23][24][25][26][27] of the origin of ultrahigh energy cosmic ray (UHECR) particles.This scenario is the most economical among the various hypotheses, because the neutrinos can penetrate cosmological distances and their trajectories are not deflected by magnetic fields as they are neutral.The Zburst scenario suggests that if ZeV astrophysical neutrino beam is sufficiently strong it can produce the observed UHECR particles within 100 Mpc by hitting local light relic neutrinos clustered in dark halos.They form such particles through the hadronic Z (s-channel production) and Wbosons (t-channel production) decays by weak interactions.The discovery of UHE neutrino sources would also clarify the production mechanism of the GeV-TeV gamma rays observed on Earth.The AGNs as significant point sources of neutrinos were analyzed, for example, in [26,28,29].While being hard to detect, neutrinos have the advantage of representing unique fingerprints of hadron interactions and, therefore, of the sources of cosmic rays.At present, a numerous reports are available in the literature on expected discovery potentials and sensitivity of experiments to neutrino point-like sources.Currently, operating high energy neutrino telescopes, see, for example, Antares [30,31], IceCube [32,33], Baikal [34], JEM-EUSO mission [35], the Telescope Array experiment [36], Pierre Auger Observatory [37,38], and so forth, attempt to detect UHE neutrinos.For example, in [32] it is reported on the first measurement of the atmospheric electron neutrino flux in the energy range between approximately 80 GeV and 6 TeV.Using data recorded during the first year of operation of IceCube DeepCore low-energy extension, a sample of 1029 events is observed in 281 days of data, of which 496 ± 66(stat) ± 88(syst) are estimated to be cascade events, including both electron neutrino and neutral current events.The rest of the sample includes residual backgrounds due to atmospheric muons and charged current interactions of atmospheric muon neutrinos.The flux of the atmospheric electron neutrinos is consistent with models of atmospheric neutrinos in this energy range.This constitutes the first observation of electron neutrinos and neutral current interactions in a very large volume neutrino telescope optimized for the TeV energy range.
This paper is organized as follows.In Section 2 we present the mass and luminosity estimates of 5 nuclear components of Mrk 261/262 and Mrk 266.Section 3 deals with the PRTsimulations for supermassive black holes in the nuclear components.In Section 4 we compute the fluxes of primary UHE neutrinos produced in the superdense protomatter medium.The concluding remarks are presented in Section 5. We will refrain from providing lengthy details of the MTBH and neutrino flux computations.For these, the reader is referred to Appendices A and B.

The Mass and Luminosity
Estimates The differences arise from the wide scatter in calibrating  BH versus luminosity or velocity dispersion.Also, there is no similar infrared spectral observation for Mrk261/262.Therefore, we are going to estimate the black hole masses in the same way from our optical spectra of Mrk261/262 and Mrk 266 [5], using the width of the [OIII]5007 line.Note that a tight correlation exists for active galaxies between the velocity dispersion  * of the bulge in a galaxy and the mass of its nuclear black hole  BH [44,45].Moreover, many groups have used the width of the [OIII]5007 line as a substitute for the stellar velocity dispersion  * of galaxy bulges.So, at the very beginning we may plot the  BH / ⊙ - * relation on logarithmic scales (Figure 1) for 17 objects chosen from [46].These objects have the most accurate  BH measurements based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data and [OIII]5007 FWHMs.Scatter about the mass-luminosity relationship for these AGNs appears to be real and could be correlated with either Eddington ratio or object inclination.The formula of the fitted solid line to the data with a scatter of ±0.42 in log is Next, from our optical spectra [5] Å).The hz44 standard star was chosen for flux calibration, and the spectral dispersion was 5.9 Å/pix.The resolution, as measured on the night sky lines, was ∼16.3 Å (FWHM).In [5], we also used the observational data of Mrk 266, obtained on the 5 m Hale telescope at Palomar Observatory with the Norris Spectrograph.Rotating the position angle by 45 degrees, each component was observed in red and blue parts at different position angles of 31 ∘ , 76 ∘ , 121 ∘ , and 166 ∘ .The pixel scale of detector was 1024 × 256 pixels for red part and 180 × 800 pixels for blue part.The exposure times amounted to 900 s for each spectrum in case of position angle 31 ∘ , but the 420 s exposures were taken for the rest of position angles.The spectral dispersions were 2.2 and 0.66 Å/pix, respectively, for spectral bands of blue part, (3750 Å) − (5500 Å), and red part, (6450 Å) − (7100 Å).
The resolution, as measured on the night sky lines, was ∼7.5 Å (FWHM) for the blue part, and ∼1.8 Å (FWHM) for Advances in Astronomy the red part.As it is seen, the nuclear components in both of these samples show quite similar emission lines in their spectra.Treating the instrumental profile and the intrinsic profile to sum as Gaussians is a good approximation [47].
A formal solution, in general, is a deconvolution, but this comes very close to the same result.Thus, unfolding wholly the forbidden [OIII]5007 line profile into its Gaussian component, the question can be resolved by subtraction of instrumental broadening (for the real Doppler broadening   of the [OIII]5007 lines see Table 1).
Bolometric Luminosity Estimate.The bolometric luminosity is not straightforward to derive for most of the AGNs because of beaming and obscuration.It was sometimes also approximated from optical luminosity, since integration of the spectral energy distribution is usually hampered by lack of wavelength coverage and by variability.In our calculation, we use the total bolometric luminosity, which, according to [48], equals 9.26 times the value of the visual luminosity   (5100 Å).For this, we need to derive the visual luminosities   (5100 Å) for the Mrk 266 and Mrk 251/262.In the first  step, we may find a correlation between the visual luminosities   (5100 Å) for 34 AGNs and black hole masses, presented in [46], which is plotted in Figure 5.The fitted line formula is with the scatter ±0.45 in log.We then looked for the visual luminosities   (5100 Å) for Mrk 266 and Mrk 251/262, which can be estimated from this relation.And then, we derive the required bolometric luminosities; see Table 2.

PRT Simulations for Mrk 261/262 and Mrk 266
In the framework of MTBH, the PRT is referred to as the earlier part of the lifetime  BH of SPC.During this time an infalling matter forms protomatter disk around the protomatter core tapering off faster at reaching out the thin edge of event horizon.That is,  BH =   / Ṁ, where Ṁ is where  OV = 13.68 km.

SPC-Configurations.
As a working model we assume the SPCconfigurations, which are discussed in [6].They are composed of spherical-symmetric distribution of matter in manyphase stratified states.The I-class SPC-configuration above the density  >   = 2.6 × 10 16 g cm −3 is thought to have central core composed of the n-p-e protomatter, which is mixture of neutrons, protons, and electrons in complete equilibrium, at short nucleon-nucleon distances  NN ≤ 0.4 fm in presence of ID.The second class SPC-configuration, above the density  >   , is thought to have protomatter core made of quarks in one bag in complete -equilibrium under the weak interactions and gluons, including the effects of QCDperturbative interactions (for details see Appendix A.1).
Modeling.With the black hole masses and bolometric luminosities given in Tables 2 and 3, we proceed to PRT-simulations.The main idea comes to solving an inverse problem.Namely, by reiterating integrations of the state equations of SPC-configurations we determine those required central values of particle concentration (0) and ID-field (0), for which the total mass of configuration obtained after integration is equal to the black hole mass estimated from observations.Among all the integral characteristics, the radius   is also computed, which is used to calculate  BH .
The results are summed up in

UHE Neutrino Fluxes
We are now in a position to compute the UHE neutrino fluxes.
We have chosen the cosmological model favored today, with a flat Universe filled with matter Ω  =   /  and vacuum where the critical energy density   = 3 2 0 /(8  ) is defined through the Hubble parameter  0 .For our calculations we have taken the values  0 = 70 km/s/Mpc, Ω  = 0.7, and Ω  = 0.3.

URCA Reactions.
In the framework of MTBH, the total UHE neutrino spectral flux of cooling of the SPC, of given mass M, by modified URCA reactions with no muons, reads (Appendix B.1), where the neutrino is radiated in a cone with the beaming angle  ∼   = /2  ,  is the thickness of the protomatter disk at the edge of even horizon and () = (1 + ) ∫ 1+ 1 / √ 2.3 +  3 .As it is seen, the nucleon modified URCA reactions can contribute efficiently only for extragalactic objects with enough small redshift  ≪ 1.

Pionic Reactions.
The pionic reactions, which occurred in the superdense protomatter medium of SPC, allow both the distorted energy and momentum to be conserved.The following is the analogue of the simple URCA processes: and the two inverse processes.As in the modified URCA reactions, the total rate for all four processes is essentially four times the rate of each reaction alone.The muons are already present when pions appear.The UHE neutrino mean flux is given (Appendix B.2) as The resulting total energy-loss rate will then be dramatically larger due to the pionic reactions (5) rather than the modified URCA processes.

Quark Reactions.
In the superdense protomatter medium, the distorted quark Fermi energies are far below the charmed -, -, and -quark production thresholds.Therefore, only up, down, and strange quarks are present.The  equilibrium is maintained by reactions like →  + which are  decay and its inverse.These reactions constitute simple URCA processes, in which there is a net loss of a ]  ]  pair at nonzero temperatures.In this application, a sufficient accuracy is obtained by assuming  equilibrium and that the neutrinos not to be retained in the medium of Λ-like protomatter.The quark reactions ( 7) and ( 8) proceed at equal rates in  equilibrium, where the participating quarks must reside close to their Fermi surface.Hence, the total energy of flux due to simple URCA processes is rather twice that of ( 7) or ( 8) alone.The total flux of UHE neutrino can be written (Appendix B.3) as 4.4.Total Flux Simulation.For total flux simulation we use the data of all the black hole mass and luminosity estimates from Table 2. Solving the inverse problem, we determine the radii and surface temperatures corresponding to these sources.The results of the computation are summed up in the Table 3, and are shown in Figures 7, 8, and 9.The last three columns present the neutrino fluxes    ( = , , ), which are the log of (    /(erg cm −2 s −1 sr −1 )).They are ranging from   ] /(  erg cm −2 s −1 sr −1 ) ≃ 1.1 × 10

Conclusions
In the framework of MTBH, we address the neutrino radiation of plausible accreting supermassive black holes closely linked to 5 nuclear components of unusual galaxy samples of Mrk261/262 and Mrk 266.This necessarily requires to estimate more accurately the values of black hole masses and bolometric luminosities for these nuclear components.
We estimate these values from our observations and predict an ∼10 Gyr time delay before neutrino emission.The UHE neutrinos with energies up to hundreds ZeV are produced in superdense protomatter medium via simple (quark and pionic reactions) or modified URCA processes, even after the neutrino trapping.The computed neutrino fluxes for quark reactions are ranging from   ] /(  erg cm −2 s −1 sr −1 ) ≃ 1.1 × 10 −9 to 8.2 × 10 −9 .For pionic and modified URCA reactions, the fluxes are   ] ≃ 0.1  ] and  URCA ] ≃ 7.4 × 10 −11   ] , respectively.These fluxes are highly beamed along the plane of accretion disk, peaked at ultrahigh energies and collimated in smaller opening angle   ∼  ∼ 10 −12 .The Mrk 261/262 and Mrk 266, therefore, may be of interest for the Z-burst scenario of origin of UHECRs.Such neutrinos may The microscopic model of AGN with central stable SPC, due to which the stable equilibrium holds in outward layers too and, thus, now an accumulation of matter allowed around SPC inside the EH.The static observers can exist inside the EH.The SPC accommodates the highest energy scale >10 21 eV in PC.With time, an infalling matter forms PD around PC tapering off faster at reaching out the thin edge of EH.At this, metric singularity cutoff [6,7] is switched on and the neutrinos of huge energies may escape through the vista to the outside world.
initiate the cascades of UHE cosmic rays via very complex chains of Z-burst interactions.Some part of UHE neutrinos may produce in accretion disk and in a torus of hot gas surrounding the AGN core the secondary electrons with huge energies.The latter, in turn, may give rise to a secondary flux of the GeV-TeV gamma rays.

A. Further Topics on the MTBH
In this section we recollect some relevant points of the MTBH [6,7] in a concise schematic form.
A.1.The Stable SPC.Discussed in [6,15,16] gravitational theory is consistent with general relativity up to the limit of neutron star.However, due to the spontaneous gauge symmetry breaking in gravity, it also manifests its virtues in density range far above nuclear density.The black hole model, presented in the framework of phenomenological and microscopic approaches, is schematically plotted in Figure 10.The equations describing the equilibrium SPC include the gravitational and ID field equations, the hydrostatic equilibrium equation, and the state equation.The latter is specified for each domain of many layered configurations.Each particle of the protomatter goes off from its original mass shell and, thus, acquires the distorted energy, momentum and mass at rest.The thermodynamics of the protomatter strongly differs from the thermodynamics of highly compressed ordinary matter.
The resulting stable SPC is formed, which consists of the protomatter core and the outer layers of ordinary matter.

SPC-Configurations in More Details.
A layering of configurations is a consequence of the onset of different regimes in equation of state.In the density range  < 4.54 × 10 12 g cm −3 , one uses for both configurations the simple semiempirical formula of state equation given by [49].Above the density  > 4.54 × 10 12 g cm −3 , for the simplicity, the I-class SPC I configuration is thought to be composed of regular neutronproton-electron (n-p-e) gas (in absence of ID) in intermediate density domain 4.54 × 10 12 g cm −3 ≤  <   and of the n-p-e protomatter in presence of ID at  >   .For the II-class SPC II configuration above the density   = 4.09 × 10 14 g cm −3 , one considers an onset of melting down of hadrons when nuclear matter consequently turns to quark matter, found in string flip-flop regime.In domain   ≤  <   , to which the distances 0.4 fm <  NN ≤ 1.6 fm correspond, one has the regular (ID is absent) string flipflop regime.This is a kind of tunneling effect when the strings joining the quarks stretch themselves violating energy conservation and after touching each other they switch on to the other configuration [6].In domain   ≤  <   , one has the string flip-flop regime in presence of ID, at distances 0.25 fm <  NN ≤ 0.4 fm.That is, the system is made of quark protomatter in complete  equilibrium with rearrangement of string connections joining them.In the final domain  >   , the system is made of quarks in one bag in complete  equilibrium at presence of ID.The quarks are under the weak interactions and gluons, including the effects of QCD-perturbative interactions.The QCD vacuum has a complicated structure, which is intimately connected to the gluon-gluon interaction.In most applications, sufficient accuracy is obtained by assuming that all quarks are almost massless inside a bag.This physical picture with appropriate modifications is adapted by [6] to the medium of quark protomatter.The latter is regarded as a noninteracting Fermi gas found in the ID region of the space-time continuum, at short distances  NN ≤ 0.25 fm.Each configuration is defined by the two free parameters of central values of particle concentration ñ(0) and dimensionless potential of space-like ID-field (0).The interior gravitational potential  int 0 () matches into the exterior one  ext 0 () at the surface of the configuration.The central value of the gravitational potential  0 (0) can be found by reiterating integrations when the sewing condition of interior and exterior potentials holds.The simulations confirm in brief the following scenario: the energy density and internal pressure have sharply increased in protomatter core (with respect to corresponding central values of neutron star) proportional to gravitational forces of compression.This counteracts the collapse, and equilibrium holds even for the masses ∼10 9  ⊙ .The most important question of stability of SPC was further studied in [7], whereas minimizing the energy Ẽ gives the equilibrium configuration.The second derivative of Ẽ gives stability information.A relativity tends to destabilize configurations.However, a numerical integration of the stability equations of SPC clearly proves the stability of resulting SPC.Note that, since SPC is always found inside the event horizon sphere, then it could be observed only in presence of accreting matter.

A.2. PRT versus Bolometric Luminosity.
In approximation   ≪   , the PRT reads In case of collisionless accretion, (A.1) gives  BH [7] as follows: For the hydrodynamic accretion [7], we get where ( 00 )  ≡  00 (  ),   is the critical sonic point outside the event horizon.The spherical accretion onto black hole, in general, is not necessarily an efficient mechanism for converting rest-mass energy into radiation.Accretion onto black hole may be far from spherical accretion, because the accreted gas possesses angular momentum.In this case, the gas will be thrown into circular orbits about the black hole when centrifugal forces will become significant before the gas plunges through the event horizon [7].According to (A.

B. UHE Neutrino Fluxes
Hereafter, the following notational conventions will be used: we denote the quantities referred to SPC by wiggles, while the corresponding quantities of neutron star or quark star are left without wiggles.The interior temperature or temperature at the surface of protomatter core is T > 100 ZeV/  ∼ 1.2 × 10 27 K [6].The SPC interiors are to a good approximation isothermal, but near the surface the temperature T drops rapidly.We may, therefore, adapt a standard discussion of the degenerate-nondegenerate transition region of a neutron star to the corresponding region of SPC.This is quick to estimate T and will guide us toward a first look at some of the associated physics.So, the surface temperature T of the SPC can be given [6] as follows: Consequently, the flux reads where  is the redshift and   () is the luminosity distance depending on the cosmological model.The (1 + ) −1 is due to the fact that each neutrino with energy Ẽ ] if observed near the place and time of emission   will be red-shifted to energy Ẽ] = Ẽ ] ( 1 )/( 0 ) = Ẽ ] (1 + ) −1 of the neutrino observed at time  after its long journey to us, where () is the cosmic scale factor.The luminosity distance is given as [26]   () = (1 + )   0 √Ω  ∫ B.2. Pionic Reactions.Note that there are two fewer fermions participating in the reactions than in the modified URCA reactions.So the phase-space factor varies as  6 rather than  8 .Continuing along the previous section, we obtain then where T = Ẽ /  ,   ] refers to the neutron star [51] as follows: ] ≃ 1.5 × 10 and the total UHE neutrino flux is then given by (6).

B.3. Quark Reactions.
Our purpose here is in sufficient approximation to adapt the discussion of ordinary quark matter in neutron star [52,53] to the corresponding region of quark protomatter in SPC.A rearrangement of vacuum state causes a shift of zero point energy of the protomatter particles.Accordingly, the energy-loss rate of the SPC due to neutrino emission process  →  +  − + ]  is generalized in the following form [6]: where p and Ẽ denote the distorted momentum and energy of a particle of the given species of protomatter.The four vectors p are numbered as  = 1, 2, 3, 4 ≡ , ]  , ,  − ,  is the normalization volume, || 2 is the squared invariant amplitude averaged over the initial -quark spin and summed over the final spins of the  quark and the electron,  ≡ [exp β( Ẽ − μ ) + 1] −1 is the fraction of phase space occupied at energy Ẽ and distorted chemical potential μ = (1 + 8  /3) p , given to the lowest order in the QCD interaction coupling constant   , p is the Fermi momentum, and  =   (1 −   )(1 −   ) is the statistical factor.The blocking factors 1 −   accounting for the distribution of final states reduce the reaction rate, which ensure that the exclusion principle is obeyed; the factor 3 takes account of three color degrees of freedom, and 2 is the spin of the initial  quark.Since typical Fermi energies of quarks are higher than the electron rest mass, a slight difference between μ and μ (or μ and μ ) implies that the electrons will generally have a relativistic Fermi energy.The interaction of Lagrangian density is given in the standard current-current form.As the neutrinos are produced thermally, we can neglect the neutrino momentum in the momentum conservation law.We may further set Ẽ ≃ p because all the particles are relativistic and that p ∼ p ( p ≪ p ).Also all the p (except p] ) can be set equal p () and removed from the integral.To estimate the magnitude of the emissivity (B.12), we follow the original argument presented in [52], which applies to both neutron star and SPC, and assume that for distorted Fermi momenta p () ≃ p () ≃ p () as in noninteracting case, such that p () ≃ 3 (1/3) Ỹ(1/3)  p (), where Ỹ ≃ ñ /ñ  , ñ is the distorted concentration of particles.We also set the value   ≃ 0.1 as rather being a reasonable order of magnitude estimate and Ỹ ≃ 0.01 as typical value of what is expected for superdense protomatter.The statistical factor is  =   (1 −   )(1 −   ) = ∏ 3 =1 (1 +    ) −1 , where the dimensionless energies   are defined  1 = β( Ẽ − μ ),  2 = − β( Ẽ − μ ),  1 = − β( Ẽ − μ ).There will therefore be [6]  where  = 16 −6    2 cos 2   ,  2 ≡ Ẽ] β, the weak-coupling constant is  ≃ 1.435 × 10 −40 erg cm 3 , and   is the Cabibbo angle (cos 2   ≃ 0.948).Recall that a standard evaluation of J in the complex plane gives [49] (1 +   2 ) J = Residue at  = 0 of [ Different Ẽ] dependence is due to the partial restriction of the electron's phase space which introduces an extra factor of ( Ẽ β) −1 .But, as far as (B.18) is independent of the electron's Fermi energy, a potential source of ambiguity is eliminated.Consequently, both (B.17) and (B.18) yield the total flux (9).

[42,43]minosity of 1.58(10.5)×10 41erg s −1 , computed from published high resolution Infrared Spectrograph on board Spitzer Space Telescope (IRS) measurements[42,43], corresponds to  BH = 1.7(3.2)×10 8 ⊙ for the SW nucleus, where the scatter is 0.46 and 0.47 in log.These values are in good agreement with the estimates based on the SW bulge luminosity.However, it should be emphasized that the available IRS data did not have sufficient spectral and spatial resolution to extract [Ne V] and [O IV] line fluxes for the NE nucleus.
