Charged Bardeen black hole with a cosmological constant and surrounded by quintessence and a cloud of strings

Exact solutions which generalize the Bardeen black hole solution, in the sense that several sources are taken into account, are derived. The most general case corresponds to a charged Bardeen black hole with a cosmological constant and surrounded by quintessence and a cloud of strings. A discussion is presented concerning the Kretschmann scalar and its dependence with the parameters associated to the different sources. Finally, the geodesics and effective potential are analyzed.

Thermodynamics and remnants of Kiselev black holes in Rainbow gravity

We do a detailed study of the thermodynamics of black holes in Rainbow gravity in the framework of the Kiselev metric, taking into account different cosmic fluids which can mimic several kinds of dark energy scenarios. A discussion related to the appearance of black hole remnants is presented and, unlike other studies on the same topic, we found no evidence of the appearance of remnants in Rainbow gravity, except in peculiar cases.
