5 Cosmological Discussion
5 Cosmological Discussion
To describe the Universe, and more precisely, the formalism of its large-scale structure and evolution. it is necessary, in addition to the description of its dynamics provided by General Relativity, to study structure formation, the Cosmic Microwave Background radiation, baryogenesis, and baryon acoustic oscillations in the early Universe. Any modification to the gravitational formalism requires a discussion of how these descriptions are affected and how they relate to the associated astronomical data.
5.1 BAO and CMB anisotropies.
The anisotropy of the cosmic microwave background (CMB) consists of the small temperature fluctuations in the blackbody radiation left over from the Big Bang. The average temperature of this radiation is 2.725 K as measured by the COBE satellite. The CMB anisotropies are the result from inhomogeneities in the distribution of matter at the epoch of recombination.
5.2 Relations Tully–Fisher and Faber-Jackson
5.3 Angular Diameter distance
5.4 Olbers’ Paradox and the extragalactic background light (EBL).
5.5 Galaxy merger
Beyond 10 Mpc the gravitational redshift remains constant in accordance with the previous assumption of the massive graviton. Then the maximum additional contribution (58) of the UYF to the redshift gravitational is 7.83 (x ≥10 Mpc) and zg increases by a factor until 88.3. This result is interesting to understand the problem of AGN at High-redshift and the nature of Quasars. Also in fig 6 (right), the variation (in logarithmic scale) of the gravitational redshift for different objects as a function of distance is shown, in particular the observation of White Dwarf's in the interior of the globular clusters could be a test for UYF . The extreme cases of high redshift are the SBH in center of galaxies, with event horizon of the order of a light-year and masses in order of the core-mass in M87 (Event Horizon Telescope Collaboration 2019). The figure 109 show the Gravitational redshift for compact objects, note that that in distance ranges of the order of one third of the range of gravity the gravitational redshift remains constant for any compact object considered, therefore, the observation of these objects outside the local group of galaxies will allow the cosmological redshifts to be calibrated. Observe that second term in (58) increase the Gravitational redshift until 7.83 and would help understand the problem of AGN at High-redshift and the nature of Quasars. An important result in (28) is that two galaxies an equal distance could be present redshift different, thus it´s solvent the Arp’s controversy (Arp, 2003).
