The paper discusses the recovery of the time evolution of dark energy (DE) using cosmologically coupled black holes (BHs) as a source. Recent baryon acoustic oscillation measurements by the Dark Energy Spectroscopic Instrument (DESI) have found evidence that DE evolves with time, parameterized by a $w_0 w_a$ equation of state. The authors show that the DESI-preferred $w_0 w_a$ models can be recovered when a $w_0 w_a$ model is fit to DE produced by baryon conversion in cosmologically coupled BHs. This recovery does not require any ad hoc parameter adjustments and is solely dependent on the independently measured cosmic star formation rate density. The study discusses the implications of this result in the context of the missing baryon problem and the anomalously low sum of neutrino masses preferred by DESI. The global evolution of DE is an orthogonal probe of cosmological coupling, complementing constraints on BH mass growth from various astrophysical sources. The paper also explores the sensitivity of the results to different star formation rate densities (SFRDs) and discusses the physical implications of the baryon consumption required in the BH DE scenario.The paper discusses the recovery of the time evolution of dark energy (DE) using cosmologically coupled black holes (BHs) as a source.
