Prospects for characterizing Population III remnants with next-generation gravitational-wave observatories
N. V. Krishnendu, Patricia Schmidt, Geraint Pratten
The most distant gravitational-wave (GW) detection by LIGO, Virgo and KAGRA so far is a binary black hole (BBH) merger at a redshift of , corresponding to a luminosity d…
Biases in Tests of General Relativity from Microlensed Gravitational-Wave Signals
Anirban Kopty, Apratim Ganguly, N. V. Krishnendu +1
Gravitational-wave (GW) observations of compact binary mergers enable precision tests of general relativity (GR) in the strong-field regime, but their reliability depends on accura…
Probing (sub-)solar-mass black holes and superspinars with current and next-generation gravitational-wave observatories
K. S. Sruthy, N. V. Krishnendu, Chandrachur Chakraborty +1
Gravitational-wave observations provide a powerful probe of compact objects and strong-field gravity. In this work, we investigate the detectability of binaries containing (sub-)so…
Testing the Kerr hypothesis beyond the quadrupole with GW241011
Rimo Das, N. V. Krishnendu, M. Saleem +2
All multipole moments of a Kerr black hole are uniquely determined by its mass and spin. Gravitational wave observations can test this prediction by measuring spin-induced multipol…
Testing general relativity with gravitational waves -- improving and extending Modified Dispersion Relation tests
Tomasz Baka, Balázs Cirok, K. Haris +2
Searching for a modified dispersion relation is one of the general relativity tests performed by the LIGO-Virgo-KAGRA collaboration with each new cumulative Gravitational Wave Tran…
Spin-induced quadrupole moment based test for eccentric binaries
N. V. Krishnendu
The spin-induced quadrupole moment-based test of black hole nature is routinely used to probe the true nature of detected binary signals, assuming a circular orbit. We extend the a…
