Geodesic structure, eikonal quasinormal modes and thermodynamic properties of a Schwarzschild-de Sitter-like black hole with global monopole in Bumblebee gravity
Irengbam Roshila Devi, Yenshembam Priyobarta Singh, Dhruba Jyoti Gogoi +1
We investigate the geodesic dynamics, eikonal quasinormal modes (QNMs), and extended phase space thermodynamics of a Schwarzschild-de Sitter-like black hole coupled with a global m…
Multi-Spin Perturbations, Thermodynamics, and Observational Signatures of Reissner-Nordstrom Black Holes in Bumblebee Gravity
Jayasri Choudhury, Yenshembam Priyobarta Singh, Dhruba Jyoti Gogoi +1
In this paper, we present a comprehensive investigation into the dynamical and thermodynamic properties of the charged Reissner-Nordström (RN) black hole (BH) in the bumblebee gra…
EGUP effects on the thermodynamic properties of the Kerr-Newman black hole surrounded by quintessence
Aheibam Boycha Meitei, Yenshembam Priyobarta Singh, T. Ibungochouba Singh +2

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…
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…
Quasinormal modes and greybody factors of charge black hole in bumblebee gravity model
Yenshembam Priyobarta Singh, Jayasri Choudhury, Telem Ibungochouba Singh +1
In this paper, we investigate the Dirac field, scalar field and electromagnetic field perturbations of Reissner-Nordstorm-de Sitter (RNdS) and Reissner-Nordstorm-(anti)-de Sitter (…
