Probing astrophysical environment with eccentric extreme mass-ratio inspirals
Mostafizur Rahman, Shailesh Kumar, Arpan Bhattacharyya
The discovery of gravitational waves and black holes has started a new era of gravitational wave astronomy that allows us to probe the underpinning features of gravity and astrophy…
Traversable wormholes in bi-metric gravity
Mostafizur Rahman, Anjan A Sen, Sunil Singh Bohra
The ghost-free bi-metric gravity theory is a viable theory of gravity that explores the interaction between a massless and a massive graviton and can be described in terms of two d…
Perturbing the perturbed: Stability of quasinormal modes in presence of a positive cosmological constant
Subhodeep Sarkar, Mostafizur Rahman, Sumanta Chakraborty
In this work, we wish to address the question -- whether the quasi-normal modes, the characteristic frequencies associated with perturbed black hole spacetimes, central to the stab…
