Probing Hairy Kerr Black Holes through Quasi-Periodic Oscillations I: A study based on the kinematic models
Anirban Dasgupta, Supragyan Priyadarshinee, Indrani Banerjee +1
Black holes endowed with nontrivial scalar or matter fields, known as hairy black holes, possess additional parameters beyond mass, charge, and spin, leading to richer phenomenolog…
Investigating the interplay of the braneworld gravity and the plasma environment on the black hole shadow
Siddharth Kumar Sahoo, Indrani Banerjee
We investigate the shadow of a rotating braneworld black hole in dispersive plasma environments and assess the potential of the Event Horizon Telescope (EHT) observations to constr…
Constraining the rotating Simpson-Visser spacetime from the observed quasi-periodic oscillations in black holes
Anirban Dasgupta, Indrani Banerjee
Regular black holes (BHs) which are singularity-free alternatives to the standard black hole paradigm in General Relativity (GR), offer effective models for probing the interface b…
Deciphering signatures of Kerr-Sen black holes in presence of plasma from the Event Horizon Telescope data
Siddharth Kumar Sahoo, Indrani Banerjee
The present work explores the role of the dilaton charge and the plasma environment in explaining the observed images of M87* and Sgr A*. Dilaton charges are associated with…
Signatures of Einstein-Maxwell dilaton-axion gravity from the observed quasi-periodic oscillations in black holes
Anirban Dasgupta, Nishant Tiwari, Indrani Banerjee
String-inspired models are often believed to provide an interesting framework for quantum gravity and force unification with promising prospects to resolve issues like dark matter…
