Cosmological black holes from self-gravitating fields
Elcio Abdalla, Niayesh Afshordi, Michele Fontanini +2
Both cosmological expansion and black holes are ubiquitous features of our observable Universe, yet exact solutions connecting the two have remained elusive. To this end, we study…
Superradiant instability of extremal brane-world Reissner-Nordström black holes to charged scalar perturbations
Shao-Jun Zhang, Bin Wang, Elcio Abdalla
We examine the stability of extremal braneworld Reissner-Nordström black holes under massive charged scalar perturbations. We show that similar to the four-dimensional case, the su…
Separating expansion and collapse in general fluid models with heat flux
Morgan Le Delliou, José Pedro Mimoso, Filipe C. Mena +3
In this paper we consider spherically symmetric general fluids with heat flux, motivated by causal thermodynamics, and give the appropriate set of conditions that define separating…
