DESI Dark Energy Time Evolution is Recovered by Cosmologically Coupled Black Holes
Kevin S. Croker, Gregory Tarlé, Steve P. Ahlen +4
Recent baryon acoustic oscillation (BAO) measurements by the Dark Energy Spectroscopic Instrument (DESI) provide evidence that dark energy (DE) evolves with time, as parameterized…
Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Duncan Farrah, Kevin S. Croker, Gregory Tarlé +16
Observations have found black holes spanning ten orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is however provisional as its behavior at i…
Implications of Symmetry and Pressure in Friedmann Cosmology. II. Stellar Remnant Black Hole Mass Function
Kevin Croker, Kurtis Nishimura, Duncan Farrah
We consider some observational consequences of replacing all black holes (BHs) with a class of non-singular solutions that mimic BHs but with Dark Energy (DE) interiors; GEneric Ob…
Cosmological tests of the gravastar hypothesis
K. A. S. Croker
Gravitational vacuum stars (gravastars) have become a viable theoretical alternative to the black hole (BH) end-stage of stellar evolution. These objects gravitate in vacuum like B…
