A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission
A. A. Araújo Filho, Arun Kumar, N. Heidari +3
We investigate the geometrical, thermodynamic, and quantum emission properties of a rotating black hole immersed in a Hernquist dark matter halo. Starting from a static black hole…
Shadows and lensing signatures of a rotating black hole in a Hernquist dark matter halo
A. A. Araújo Filho, Arun Kumar, N. Heidari +3
We investigate the optical properties of a rotating black hole immersed in a Hernquist dark matter halo. The spacetime is generated from a static Hernquist black hole through the n…
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…
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…
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…
Probing Loop Quantum Gravity black holes through gravitational lensing
Arun Kumar, Qiang Wu, Tao Zhu +1
We investigate strong gravitational lensing by a charged loop quantum gravity (LQG) black hole obtained through the polymerisation scheme of Borges \textit{et al.} \cite{Borges:202…
