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…
Probing Lorentz Symmetry Violation through Lensing Observables of Rotating Black Holes
Arun Kumar, Shafqat Ul Islam, Sushant G. Ghosh
We find a Kerr-like black hole solution-a rotating Bumblebee black hole (RBBH) with a Lorentz-violating parameter and examine the strong lensing by it. The parameter …
Lyapunov Exponent Approach to Phase Structure of Schwarzschild AdS Black Holes Surrounded by a Cloud of Strings
Arun Kumar, Qiang Wu, Tao Zhu +1
We investigate Schwarzschild black holes in anti-de Sitter (AdS) spacetimes surrounded by a cloud of strings (BH-AdS-CoS), incorporating both electric- and magnetic-like components…
The Influence of Uniform Magnetic Fields on Strong Field Gravitational Lensing by Kerr Black Holes
Amnish Vachher, Arun Kumar, Sushant G. Ghosh
We investigate strong gravitational lensing using magnetized Kerr black holes (MKBHs), which are accurate Kerr-Bertotti-Robinson solutions for Kerr black holes in a uniform magneti…
