Line-of-sight Acceleration Driven Effects in Eccentric Compact Binary Coalescences
Mohd Asim Ansari, Avinash Tiwari, Sajad A. Bhat +2
The line-of-sight acceleration (LOSA) effect, imprinted in the gravitational wave (GW) signal of an inspiralling compact binary by an external gravitational potential, is one of th…
Tidal Stripping of Matter Bound to the Secondary in Extreme Mass-Ratio Inspirals
Sreejith Nair, Sayak Datta
Environmental studies of extreme mass-ratio inspirals (EMRIs) have focused almost entirely on matter surrounding the primary supermassive black hole. We instead consider matter bou…
Plunge spectra as discriminators of black hole mimickers
Sreejith Nair
This work explores the prospect of using the plunge to identify potential black hole mimickers. We show that the plunge excites two generic spectral features. (i) At low frequencie…
Bounds on the charge of the graviton using gravitational wave observations
Sreejith Nair, Aditya Vijaykumar, Sudipta Sarkar
If the graviton possesses a non-zero charge , gravitational waves (GW) originating from astrophysical sources would experience an additional time delay due to intergalactic ma…
Asymptotically de-Sitter black holes have non-zero tidal Love numbers
Sreejith Nair, Sumanta Chakraborty, Sudipta Sarkar
Love numbers of compact objects quantify their tidal deformability against external perturbations. It is expected that Love numbers of asymptotically flat black holes (BHs) in Gene…
Does the speed of gravitational waves depend on the source velocity?
Rajes Ghosh, Sreejith Nair, Lalit Pathak +2
The second postulate of special relativity states that the speed of light in vacuum is independent of the emitter's motion. The test of this postulate so far remains unexplored for…
Dynamical Love for area quantized black holes
Sreejith Nair, Sumanta Chakraborty, Sudipta Sarkar
We study the tidal deformability of horizonless exotic compact objects, with implications for area quantized black holes. Since, any such horizonless compact object, including area…
The Black hole Black string phase transition in Einstein-Gauss-Bonnet gravity
Sreejith Nair, Vardarajan Suneeta
We investigate the presence of a black hole black string phase transition in Einstein Gauss Bonnet (EGB) gravity in the large dimension limit. The merger point is the static spacet…
