Quasinormal Ringdown and Echoes in Accreting Exotic Compact Objects
Chanchal Sharma, Kabir Chakravarti, Sudipta Sarkar
Exotic compact objects (ECOs) may produce late-time gravitational-wave (GW) echoes, but sufficiently compact ECOs undergoing realistic accretion may eventually form an event horizo…
The impact of the formation channel on gravitational-wave-galaxy cross-correlations
Kabir Chakravarti, Federico R. Urban
The angular, harmonic cross-correlation between gravitational wave (GW) events and galaxy catalogues contains rich information on the large-scale structure and the origin of compac…
Tidal Love numbers and quasi-normal modes of the ECO in a Dark Matter halo
Kabir Chakravarti, Chiranjeeb Singha
It is well-known that exotic compact objects (ECOs) are a class of objects categorised as Black Hole (BH) mimickers. ECOs have been shown to possess signatures distinguishing them…
Generalized Perturbed Kepler Problem: Gravitational Wave Imprints from Eccentric Compact Binaries
Rajes Ghosh, R. Prasad, Kabir Chakravarti +1
Observations of astrophysical binaries may reveal departures from pure Keplerian orbits due to environmental influences, modifications to the underlying gravitational dynamics, or…
Effect of ultralight dark matter on compact binary mergers
Kabir Chakravarti, Soham Acharya, Sumanta Chakraborty +1
The growing catalogue of gravitational wave events enables a statistical analysis of compact binary mergers, typically quantified by the binary merger rate density. This quantity c…
Parameterized Non-circular Deviation from the Kerr Paradigm and Its Observational Signatures: Extreme Mass Ratio Inspirals and Lense-Thirring Effect
Rajes Ghosh, Kabir Chakravarti
Recent gravitational wave observations and shadow imaging have demonstrated the astonishing consistency of the Kerr paradigm despite all the special symmetries assumed in deriving…
Mergers of hairy black holes: Constraining topological couplings from entropy
Kabir Chakravarti, Amit Reza, Leonardo G. Trombetta
Hairy black-holes are a unique prediction of certain theories that extend General Relativity (GR) with a scalar field. The presence of scalar hair is reflected non-trivially in the…
Formation and Stability of Area Quantized Black Holes
Kabir Chakravarti, Rajes Ghosh, Sudipta Sarkar
We investigate the ergoregion instability of area-quantized rotating quantum black holes (QBH) under gravitational perturbation. We show that the instability can be avoided in bina…
