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…

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…

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…
