Dynamics, Ringdown, and Accretion-Driven Multiple Quasi-Periodic Oscillations of Kerr-Bertotti-Robinson Black Holes
G. Mustafa, Orhan Donmez, Dhruba Jyoti Gogoi +3
We study the motion of test particles around the Kerr--Bertotti--Robinson (KBR) black hole (BH) and explore how the three defining parameters, the mass , rotation parameter ,…
Periodic orbits as probes of charged loop quantum gravity black holes through gravitational waves
Abolhassan Mohammadi, Arun Kumar, Hongwei Tan +1
Gravitational waves from extreme-mass-ratio inspirals (EMRI) provide a direct probe of the strong-field geometry of black holes. Motivated by this, we study the motion of test part…
Testing loop quantum gravity through EHT observations of M87* and Sgr A* using rotating holonomy-corrected black holes
Heena Ali, Sushant G. Ghosh
The Event Horizon Telescope (EHT) has provided a new tool for testing the strong-field regime of gravity by imaging the shadows of M87* and Sgr A*. These observations provide the f…
Probing Gravitational Wave Signatures from Periodic Orbits of Regular Black Holes in Asymptotically Safe Gravity
Arun Kumar, Abolhassan Mohammadi, Sushant G. Ghosh
We investigate bound and periodic timelike geodesics and their associated gravitational-wave (GW) signatures in the spacetime of a regular black hole arising in asymptotically safe…
Probing Kalb-Ramond gravity with charged rotating black holes: constraints from EHT observations
Towheed Ahmad Nengroo, Shafqat Ul Islam, Sushant G. Ghosh
The Event Horizon Telescope (EHT) has guided strong-field gravitational physics by providing the first direct images of the supermassive black holes M87* and Sagittarius A*. The EH…
Thermodynamics and phase transitions of charged-AdS black holes in dRGT massive gravity with nonlinear electrodynamics
Mohd Rehan, Arun Kumar, Tuan Q. Do +1
Investigating black holes in modified theories of gravity offers fertile ground for exploring phenomena beyond the scope of general relativity. We investigate a novel class of char…
