Universal Ladder Structure Across Scales: From Quantum to Black Hole Physics
Rajes Ghosh, Rajendra Prasad Bhatt, Sumanta Chakraborty +1
Second-order ordinary linear differential equations appear ubiquitously across physics, describing the behavior of systems from the quantum world of atoms to the classical world of…
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…
Rotating black holes experience dynamical tides
Rajendra Prasad Bhatt, Sumanta Chakraborty, Sukanta Bose
We find the dynamical tidal response of a Kerr black hole (BH) and demonstrate its tidal Love numbers to be non-vanishing when present in a non-axisymmetric external tidal field. T…
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…
