GUP-corrected black holes: Thermodynamic properties, evaporation time and shadow constraint from EHT Observations of M87* and Sgr A*

H. Chen, S. -H. Dong, E. Maghsoodi +4

In this manuscript, we implement the generalized uncertainty principle (GUP) with linear and quadratic moment for Schwarzschild black hole metric in order to study the influence of…

Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics

C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3

In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…

Three dimensional black bounces in gravity

Marcos V. de S. Silva, Manuel E. Rodrigues, C. F. S. Pereira

We investigate the existence of black bounce solutions in dimensions within the framework of gravity. We analyze whether black bounce geometries originally obtained in…

Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole

C. F. S. Pereira, H. Belich, A. R. Soares +3

In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…

Roche limit and stellar disruption in the Simpson--Visser spacetime

Marcos V. de S. Silva

Due to the tidal forces that a black hole can produce, certain types of compact objects may undergo disruption as they approach the black hole. This disruption point is known as th…
