Observational Features of Nonsingular Rotating Black Holes in the Dark-Energy Dominated Universe
Ramon Torres
Recent DESI baryon acoustic oscillation measurements, combined with cosmic microwave background and type-Ia supernova data, suggest that dark energy may evolve with cosmic time. Al…

An analogue first law for general closed marginally trapped surfaces
Ramon Torres
We formulate an analogue transverse first law for general closed marginally trapped surfaces in arbitrary spacetimes. The construction is intrinsically quasi-local and is attached…

Nonsingular Rotating Black Holes in the Dark-Energy Dominated Universe
Ramon Torres
Motivated by quantum-gravity scenarios that replace the classical black hole singularity with a regular core, and by the possibility that the dark-energy sector may be scale depend…
