Strong Lensing and Quasinormal modes of black hole around global monopole

Irengbam Roshila Devi, Ningthoujam Media, Yenshembam Priyobarta Singh +1

In this paper, we investigate various key aspects of a static and spherically symmetric black hole with global monopole. Firstly, we analyze the deflection angle in the strong fiel…

Thermodynamics and null-geodesic of the Kerr-Newman black hole surrounded by quintessence and a cloud of string

Aheibam Boycha Meitei, Yenshembam Priyobarta Singh, Telem Ibungochouba Singh +2

In this paper, we study the effect of the modified dispersion relation (MDR) on the thermodynamics of the Kerr-Newman black hole surrounded by quintessence and a cloud of string. T…

Strong lensing and Hawking spectra of charged black hole under Lorentz violation theory

Yenshembam Priyobarta Singh, Ningthoujam Media, Telem Ibungochouba Singh

In this paper, we investigate the strong gravitational lensing effects around the Reissner-Nordstr{ö}m-like black hole (RN-like BH) in bumblebee gravity. We calculate the lensing q…

Entropy correction and quasinormal modes of slowly rotating Kerr-Newman-de Sitter-like black hole in bumblebee gravity

Ningthoujam Media, Y. Priyobarta Singh, Y. Onika Laxmi +1

In this paper, we study the tunneling of fermion particle for slowly rotating Kerr-Newman-de Sitter-like (KNdS-like) black hole in bumblebee gravity model by applying the generaliz…

Maxwell's equal-area law for Vaidya-Bonner-de Sitter black hole under Lorentz invariance violation

Yenshembam Priyobarta Singh, Telem Ibungochouba Singh, Sapam Niranjan Singh

In this paper, we investigate the tunneling of fermions with arbitrary spin near the event horizon of non-stationary Vaidya-Bonner-de Sitter black hole (VBdS) in Lorentz invariance…
