Fermi Degenerate Antineutrino Star Model of Dark Energy

Figure 3

Density-redshift profile, and relative contributions to the redshift by gravitational potential and radial velocity. In the ATLAS model, redshifts at low-z are mainly due to radial velocity (dashed curve) and at high-z due to time dilation of free-falling sources in the gravitational potential φ (solid curve). The density (dotted curve) acts as a form of dark energy density and vanishes at the antineutrino star’s radius, R = 21.1 Gly (or z = 2.49). This plot is based on calculations using the best-fit parameters found in the following section.
