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…

A New Approach for Calculation of Quasi-Normal Modes and Topological Charges of Regular Black Holes
MY Zhang, F Hosseinifar, H Chen +2
This study examines the properties of a special regular black hole. This analysis investigates the Hawking temperature, remnant radius and mass, as well as the effect of parameter…

Shadows, greybody factors, emission rate, topological charge, and phase transitions for a charged black hole with a Kalb-Ramond field background
F. Hosseinifar, A. A. Araújo Filho, M. Y. Zhang +2
In this work, we investigate a spherically symmetric charged black hole in the presence of a Kalb--Ramond field background. We calculate the photon sphere and shadow radii and, cor…
