Charged Bardeen black hole with a cosmological constant and surrounded by quintessence and a cloud of strings
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +2
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 char…
Charged Hayward black hole with a cosmological constant and surrounded by quintessence and a cloud of strings
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +1
A family of exact solutions extending the Hayward black hole by incorporating multiple sources is obtained. The most comprehensive scenario describes a charged Hayward black hole w…
The sound of quintessence: analogue Kiselev acoustic black holes
Luis C. N. Santos, H. S. Vieira, Franciele M. da Silva +1
In this work, we demonstrate that the geometry of a spherically symmetric black hole surrounded by a Kiselev anisotropic fluid can be effectively mimicked by an experimental setup…
Some remarks on Frolov-AdS black hole surrounded by a fluid of string
F. F. Nascimento, V. B. Bezerra, J. M. Toledo +2
A class of new solutions that generalizes the Frolov regular black hole solution is obtained. The generalization is performed by adding the cosmological constant and surrounding th…
Black holes as gravitational mirrors
L. C. N. Santos, F. M. da Silva, C. R. Muniz +1
Retrolensing is a gravitational lensing effect in which light emitted by a background source is deflected by a black hole and redirected toward the observer after undergoing nearly…
