Joule-Thomson effect and Efficiency of deformed AdS-Schwarzschild black hole in presence of quintessence
Dhruba Jyoti Gogoi, Ronit Karmakar, Jyatsnasree Bora +2
We study the Joule-Thomson expansion and extended thermodynamics of a modified black hole characterised by the parameters , , and . Analysis of the Hawking temperature, Jo…
Strong Lensing Effect and Quasinormal Modes of Oscillations of Black Holes in Gravity Theory
Gayatri Mohan, Ronit Karmakar, Rupam Jyoti Borah +1
In this work, we analyze the strong lensing phenomenon and quasinormal modes (QNMs) in the case of black holes (BHs) surrounded by fluids within the framework of gravity,…
Quasinormal modes, thermodynamics and shadow of black holes in Hu-Sawicki f(R) gravity theory
Ronit Karmakar, Umananda Dev Goswami
We derive novel black hole solutions in a modified gravity theory, namely the Hu-Sawicki model of gravity. After obtaining the black hole solution, we study the horizon radi…
Quasinormal modes, temperatures and greybody factors of black holes in a generalized Rastall gravity theory
Ronit Karmakar, Umananda Dev Goswami
We introduce a modification in the energy-momentum conservation violating Rastall's theory of gravity and obtain a Reissner-Nordström-type black hole solution in spacetime surround…
Thermodynamics and Shadows of GUP-corrected Black Holes with Topological Defects in Bumblebee Gravity
Ronit Karmakar, Dhruba Jyoti Gogoi, Umananda Dev Goswami
In this work we investigate a Schwarzschild-type black hole that is corrected by the Generalized Uncertainty Principle (GUP) and possesses topological defects within the framework…
Quasinormal modes and thermodynamic properties of GUP-corrected Schwarzschild black hole surrounded by quintessence
Ronit Karmakar, Dhruba Jyoti Gogoi, Umananda Dev Goswami
We study the Quasinormal Modes (QNMs) of the Schwarzschild black hole surrounded by a quintessence field after implementing the quantum corrections to its solution as required by t…
