Galaxy Formation With Dark Matter and Dark Energy

Eliptical and bulge galaxies share a tight correlation of velocity distribution to both luminosity and black hole mass. There are similar orbital speeds for all galaxies of a given luminosity including dark matter (DM) at large radii. The halo surface density of DM is constant for almost all types of galaxies and ranges 14 mag. down to dwarf spherical galaxies. There are supermassive black holes or giant, pure disk galaxies at high redshift inexplicable with hierarchical clustering or collapse dynamics. These and a myriad of other galaxy formation problems are explainable by an initial shell which caused the Planck cosmic microwave background radiation. A reduction in the energy-density of primordial galactic black holes is necessary to explain dark energy.

General relativity has been most successful in explaining the universe except in extreme density conditions: the big bang and black holes. Among the big bang problems is the generating massive galactic structure with an entirely hot model in the first billion years. Galaxies are constructed similarly despite their origins being physically too far apart to be in causal contact (the horizon problem). Initial spacetime was Minkowskian, that is the expansion energy exactly matched the gravitational energy (the flatness problem). The hot synthesis of the light elements of hydrogen, helium and their isotopes occurred in only about 4% of the initial matter present. Extrapolation of general relativity in black holes has resulted in infinities in the density and gravity in these structures (singularities). Here is shown much evidence that there is a loss of energy at supranuclear densities. This will allow a cold shell with a hot core to form. The emitted light will have an appropriate (Planck) spectrum, galactic structure will result in the early universe and this loss of energy will later be manifested in galactic black holes as dark energy.

Galaxy Formation Properties and Problems
Although the ΛCDM model is quite successful on supragalactic scales [1], its predictions of galactic properties differ markedly with observation. Galaxies come in two basic types: spirals which are disk shaped and ellipticals which are football shaped. The accepted theory is that the present universe grew from small inhomogeneities. These grew into larger halo structures by attracting surrounding matter. The fate of these halos is determined either by radiative cooling or gravitational heating. In low mass halos, cooling predominates, which allows cold gas to fall into the center and become disks and stars [2]. The cooling problem is most acute in galaxies. At the end of their lives, massive stars return 30 − 40% of their mass to the interstellar media. If even a small fraction of this mass is accreted, it would result in much larger black holes than are present. Gravitational heating dominates once a halo mass of about 10 12 M ⊙ is reached. Cold gas is no longer able to accrete onto galaxies. The only way galaxies within halos can grow at this stage is by mergers. Pure disk galaxies form bulges after the mergers. Yet some samples of giant galaxies have found over half are large pure disk type, without any evidence of mergers [3].
In galaxies with bulges, the mass of the central black hole correlates with the mass of the bulge and also the average spread of velocities of the bulge stars. This includes ellipticals which have bulges but no disks [4]. The mechanisms for these correlations are not known. Another problem is why the gas that formed bulge stars settled near the black hole. Part increased the black hole mass and part led to explosions that blew the gas away and suppressed star formation. Many components of galaxies besides black holes are highly correlated. The mass distribution of spiral galaxies is evenly spread from its dark matter outer limits to its inner baryonic areas. Dark matter played a strong role in the disk and stars but not its black hole. In pure disk galaxies with pseudobulges, the central black hole does not correlate with the pseudobulge [5]. Another puzzle is the reason for the inward movement of matter to the black hole in some galaxies and to the pseudobulge in others. In accepted galaxy formation theory, both galaxies with and without bulges grew by accreting matter during the period that the massive early stars were forming. These early stars would not have settled in disks because they could not be slowed enough to reside in disks. Galactic bulges do contain old stars but there is no reason these old stars avoided bulgeless galaxies. There is no evidence that they are in diffuse stellar halos either [4]. Evidently they played little role in galaxy formation. The DM halo mass distribution for galactic systems ranging from dwarf discs and spheroidals to spirals and ellipticals is essentially constant [6]. This amazing result also spans almost the whole galaxy magnitude range M B from −8 to −22 and gaseous to stellar mass fraction range of many orders of magnitude.
where µ 0D is the central surface density and is defined as r 0 ρ 0 . r 0 is the halo core radius and ρ 0 is the central density.
Simulations of galaxy formation usually start with a set of hot gravitating point particles with given initial conditions which are then stepped forward in time using huge computer resources. The Jeans mass is thought to be the point at which gravity overcomes pressure and expansion to form galactic structure. Collapse dynamics produces different post collapse densities, circular speeds and disk asymmetries. Both collapse and hierarchical clustering approaches have been unable to solve the many problems which are summarized here from [7]. 1. Is the absence of a feature in galaxy rotation curves at which the dominant source of central attraction changes from luminous matter to dark. Many galaxies are now known in which the rotation curve does drop somewhat at the edge of the visible disk, but it is extremely rare for the drop to exceed about 10%. A featureless rotation curve is expected if DM dominates galaxies right to their centers, but it is much harder to understand why the circular orbital speed from the luminous matter, which dominates the inner region, should be so similar to that from the DM at larger radii. For any galaxy dominated by stars in its center, initial conditions for the dark and luminous matter must be finely tuned to produce a flat rotation curve. 2. Extreme low-SB galaxies lie on the same Tully-Fisher relation (TFR) derived from high-SB galaxies, with somewhat greater scatter. There are similar circular speeds in all galaxies of a given luminosity, no matter how widely the luminous material is spread. This unusual result requires that the overall mass to light ratio (M/L) of the galaxy rises with decreasing SB in just the right way so as to preserve a tight relation between total luminosity and circular speed. Either the true M/L of the stellar population changes with surface brightness, which seems unlikely, or the DM fraction rises as the luminous surface density declines. The needed variations would be minor if DM dominated in all galaxies, but since stars dominate the mass in the inner parts of high-SB galaxies, eliminating the SB dependence again requires careful tuning. 3. Mass discrepancies begin to be detectable only when the acceleration drops below ∼ 10 −8 cm/s 2 . Any DM model must reproduce this characteristic acceleration scale over a wide range of galaxy sizes. 4. Aside from the disk M/L, DM halo fits to rotation curves generally employ two extra parameters: e.g. the core radius and asymptotic velocity, or the scale radius and concentration index. Actual galaxy rotation curves do not require all this freedom, however, since they can be fitted with only the disk M/L as a parameter. Any DM model must therefore contain a physical mechanism that relates the halo parameters to the luminous mass distribution. 5. A merging hierarchy causes the cooled baryonic fraction to lose angular momentum to the halo, making disks that are too small. The predicted angular momentum of the disk is at least an order of magnitude less than that observed. The problem is only partially ameliorated if some process (usually described as feedback from star formation) prevents most of the gas from cooling until after the galaxy is assembled. While this difficulty is best known within the CDM context, merging protogalaxies in any hierarchical structure formation model with DM will involve chronic angular momentum loss to the halos. 6. Every collapsed halo should manifest the same peak phase space density, if DM is collisionless, was initially homogeneously distributed, and had an initially finite value (Liouvilles theorem). Further, the finite central density of galaxy halos also suggests that halos collapsed from material having an initially finite value (infinite initial phase space density forms cusped halos) allows it to be estimated easily. Its spectacular variation between galaxies indicates that DM cannot be a simple collisionless particle. 7. High-resolution simulations that follow the formation and evolution of individual galaxy halos in CDM find strongly cusped density profiles even before the baryonic component cools and settles to the center. No observational evidence requires halos to have the predicted cusps. Further, the concentration index has a wide range but most fits to rotation curves yield values well below the predicted range in all types of galaxy, even the Milky Way. 8. There is a failure to predict the zeropoint of the Tully-Fisher relation (TFR). This is a major problem for the ΛCDM paradigm. No matter what M/L is assumed for the disk, the predicted circular speed at a given luminosity is too high because the halo density is too high. 9. Simulations produce numerous sub-clumps within large DM halos. The clumps are more numerous than the numbers of observed satellite galaxies, and may threaten the survival of a thin disk in the host galaxy. 10. The TFR discrepancy is even worse, since CDM predicts L ∝ V 3 . If V is interpreted as the circular velocity of the flat part of the rotation curve, the true relation is very nearly L ∝ V 4 . Any mechanism which systematically boosts luminosity as a function of mass must also reproduce the very small scatter in the TFR. 11. The DM halos that form in simulations are generally tri-axial, but become nearly oblate in their inner parts when a disk is added. Current constraints on halo shapes are generally thought to be consistent with these predictions. However, the halo of NGC 2403 seems to become more nearly axisymmetric at larger radii, opposite to the CDM expectation, and IC 2006 seems impressively round at 6R e . 12. The CMBR problem that was originally listed has changed as more accurate analyses have emerged. There is another problem which seems most difficult for both the hierarchical merger and collapse theories of galaxy formation. This is the finding of a galaxy with a supermassive black hole of two billion solar masses at a redshift z = 7.085, just 770 million years after the big bang [8]. Finding supermassive black holes in galaxies at high redshift have always been a problem for accepted galaxy formation methods and totally hot big bang models, but a finding this early makes it acute.

Galaxy formation with primordial black holes
A shell of baryonic matter can supply the seeds to initiate massive black holes and capture hot expanding core gases along with smaller shell matter for the haloes. The deeper the gravitational wells, the higher the velocity and more orbiting mass that could be captured. The capturing process described here is divided by distance from the primordial black holes.
Outside the immediate area of black hole influence, capturing of hot core matter streaming through the area of influence of each black hole is due to the amount of energy each particle possesses. Large kinetic energies result in hyperbolic or parabolic type orbits with the ability to escape any given gravitational well. Lower energies result in stable elliptical or circular orbits.
where E is the total energy, both kinetic and potential. l is the angular momentum, M is the central black hole mass and and m is the rotational mass. If e < 1 and E < 0, the orbit is an ellipse and the matter will be captured. Circular orbits where e = 0 and E = −mk 2 /2l 2 have even less energy. Matter that is captured has the potential energy greater than the kinetic, GmM r > l 2 mr 2 + and e < 1. Expanding the total kinetic energy E in the equation for e, e = 1 + 2l 2 (l 2 /mr 2 + 1 2 mṙ 2 − GmM/r) mk 2 Orbiting matter has e < 1 and real. If we let the angular momentum l = mrθ 2 and k = mMG, the equation for e becomes To simplify this equation, we can useθ =ṙ/r. The equation for e becomes e = 1 + 2r 2ṙ4 As GM =ṙ 2 r, then the galactic well will deepen as M ∝ṙ 2 or M ∝ r. The last term in equation above becomesṙ 8 /M 2 G 2 . When this term is dominant, it will allow capturing matter withṙ to increase as the fourth power as the galactic black hole M increases,ṙ ∝ M 4 . This explains the Tully-Fisher and Ferrarese-Merritt [9] relations. The black hole capturing cross sectional area, M csa ∝ M gravity since both scale as r 2 . Other factors during galaxy formation may include accretion due to collisional losses, ionized plasma repulsion and magnetic interference.

The quantity r in the next equations is the Schwarzschild coordinate. and Stable orbits are possible forL > 2 √ 3M. The above equations are for nonrotating or slowly rotating black holes.

Changes In Our Universe
A cold baryonic shell surrounding a hot core can absorb and not reflect hot core photons. It comprised a cavity close to the characteristic of a perfect black body with resulting radiation in thermal equilibrium as shown in Figure 1. Whether released from a small hole or the massive break up of the shell, subsequent light emission would have a Planck spectrum, like the CMBR. The emitted light was homogeneous, isotropic, unpolarized and had power emitted at an angle to the normal, proportional to the projected area. The spectral energy density was where k B is Boltzmann's constant. The first term on the right represents the number of electromagnetic modes of the standing waves at frequency ν per volume of cavity. The second term represents the average energy per mode at this frequency. For a derivation of Planck cavity radiation, see [11]. This model is fully consistent with the latest seven year CMBR study by WMAP [12], including primordial power spectum and Gaussianity, neutrino properties, helium abundance, parity violation, dark energy, and polarization. Only the dark matter are cold baryons. The finding of a constant DM halo surface density across all types and sizes of galaxies confirms that this part must have been the first to form. As the big bang unfolded, the shell ruptured as fragments, large and small, were propelled into the universe. Blacks holes were formed from the larger parts. As the higher velocity hot core matter followed, angular momentum was preserved by the gravitational capturing process. Black holes form at densities The smallest black holes that have been found in the present universe are all above 4.3M ⊙ , leaving a gap above the most massive neutron stars [13]. There must be a limiting supranuclear mass density of ρ ≈ 2.4 × 10 16 g/cm 3 . After all the space is squeezed out of nucleons, it must cost energy to collapse further. This possibility was discussed in Misner, Thorne and Wheeler [10], the Bible on gravitation, page 627. Our galaxy shows evidence of this energy and gravitational loss tunneling out of the central black hole after billions of years. There is a lopsided thickness in the outer disk of the Milky Way, which is about twice as large in one side as the other, despite the spherically symmetric distribution of galactic dark matter [14]. The tunneling of particle waves and the resulting net loss of energy and gravity is shown in Figure 2. This late energy loss can be seen as well in the measured supernova distances. The 3-geometry dσ 2 = g ij (t, x t )dx i dx j of each hyperspace is expected to be the same due to homogeneity of the universe. The initial hypersurface S I 3geometry is γ ij x K ≡ g ij (t I , x K ). At time t I on surface S I , they are separated by the proper distance ∆σ(t I ) = (γ i , ∆x i ∆x j ) 1/2 . At some later time t f , they will be separated by some other proper distance ∆σ(t f ). When spacetime is isotropic, then the ratio of ∆σ(t f )/∆σ(t I ) will be related to the universe expansion a(t f )/a(t I ). The loss in energy and gravitation will cause galaxies to wander off the Hubble flow with greater distances measured between them and is known as dark energy. This is demonstrated in Figure 3. This density limitation is also involved during supernova collapses. Although the large production of neutrinos will slow or stop a shock front, an incompressible core is necessary to restart it as a bounce. To calculate the standard electromagnetic energy density where ǫ is the total density of mass-energy, S is the total flux of mass-energy or momentum density and B and E are magnetic and electric fields, respectively. The stress-energy tensor is or eqivalently As core density reached ρ ≥ 2.4 × 10 16 space was eliminated from the nucleons. As the collapse proceeded, energy was stored in core quark compression, an energy sink. Finally the entire structure's gravitational energy was concentrated in the core. This stored potential energy was released as kinetic energy when the shell broke up, allowing nucleosynthesis only in the core matter. The energy sink caused the mass-energy of the entire structure to be zero. With this change, energy and momentum remain balanced so that the divergence ∇ · T = 0. In black holes the lapse (of time) function, black hole proper time to universal time, α ≡ dτ /dt is thought to be zero [15]. Using the dark energy time of manifestation in our universe, α ∼ 2 × 10 −16 , small but not zero. Supporting the density limitation, neither small black holes less than 4M ⊙ nor Hawking radiation has been found. The stress-energy tensor T jk will remain a second order symmetric tensor like the Einstein curvature tensor G jk , and both will be zero until the breakup of the shell. The universe did not become approximately isotropic and homogeneous until hours after the big bang as the hot core gases were captured by the black holes forming protogalaxies. Only after this period will Alexander Friedmann's equations with time derivatives of the universe scale factor become valid. With a density limitation in the stress-energy tensor, general relativity can be valid from the very beginning of the universe and throughout black holes. Halo parameters are related to the luminous mass distribution since all rotating mass was captured by a given size black hole as shown in Figure 4. An entirely baryonic model explains why the circular orbital speed from luminous matter, which dominates the inner regions, is so similar to dark matter at larger radii. With many stars in the center areas, initial conditions for dark and luminous matter no longer have to be closely adjusted to produce a flat rotation curve. A core based expansion can be captured by the similarly sized black holes, explaining why there are similiar circular speeds in all galaxies of a given luminosity no matter how the luminous matter is spaced. The overall mass to light ratio rises with decreasing surface brightness so as to preserve the Tully-Fisher relation between total luminosity and circular speed. The depth of the gravitational well determines the circular speed and luminosity. The hot and cold matter discrepancies are detectable only at accelerations below ∼ 10 −8 cm/sec 2 since they are all baryons. Collapse dynamics seems unnecessary in initial galaxy formation except possibly in pseudobulge galaxies. The peak phase space density of the halo varies so markedly as baryonic dark matter is not collisionless and was never homogeneously distributed. Both shell and core baryons are included. The predicted circular speed at a given luminosity is high. The capturing of slower velocity matter allowed an increase in kinetic energy as it fell into the gravitational well. It is not directly related to mass to light ratio or halo density. The number of predicted subclumps in the halos is so much greater than observed as well as predicted clumps compared to satellite galaxies because of the capturing process rather than collapse dyamics. As shown above, the luminosity can be related to circular velocity to the fourth power. Primordial massive black holes can efficiently remove intergalactic and intercluster matter in the early universe.

Discussion
General relativity has been extrapolated in black holes and the big bang to enormous energies and densities without sufficient supporting data. Us-ing evidence of a limitation in the stress-energy tensor, a viable big bang model can be produced, early and accurate galaxy formation can be obtained, black holes can lose information, and dark matter and dark energy can be explained. This should remove the conflict between quantum physics and general relativity and greatly simplify a theory of everything.
