Probing the spin of compact objects with gravitational microlensing of gravitational waves
Gopalkrishna Prabhu, Uddeepta Deka, Sumanta Chakraborty +1
Propagating gravitational waves (GWs) can encounter a massive object (lens) whose gravitational radius is comparable to the wavelength of the GWs (wave-optics regime). The resultin…
Probing the existence of a minimal length through compact binary inspiral
N. V. Krishnendu, Aldo Perri, Sumanta Chakraborty +1
Existence of a minimal length in spacetime geometries avoids several singular situations involving quantum theory and gravity. In this work, we show that the existence of such a mi…
Extreme mass ratio inspirals in rotating dark matter spikes
Soumodeep Mitra, Nicholas Speeney, Sumanta Chakraborty +1
Gravitational wave (GW) signals from extreme mass ratio inspirals (EMRIs) are a key observational target for the Laser Interferometer Space Antenna (LISA). The waveforms may be aff…
Gravitational physics in the context of Indian astronomy: A vision document
P. Ajith, K. G. Arun, Sukanta Bose +13
Contributions from the Indian gravity community have played a significant role in shaping several branches of astronomy and astrophysics. This document reviews some of the most imp…
Response of a Kerr black hole to a generic tidal perturbation
Rajendra Prasad Bhatt, Sumanta Chakraborty, Sukanta Bose
We derive the response, the real part of which provides the tidal Love numbers, for non-extremal as well as extremal Kerr black holes under generic tidal perturbations. Our results…
Tidal Love numbers and quasi-normal modes of the Schwarzschild-Hernquist black hole
Sumanta Chakraborty, Geoffrey Compère, Ludovico Machet
We derive the model of the Schwarzschild black hole immersed into a dark matter halo with a relativistic Hernquist profile, the Schwarzschild-Hernquist black hole, and obtain its t…
