Identifying intermediate mass binary black hole mergers in AGN disks using LISA
Poulami Dutta Roy, Parthapratim Mahapatra, Anuradha Samajdar +1
We show that Laser Interferometer Space Antenna can uniquely identify the sites of intermediate-mass binary black hole (IMBBH) mergers if they occur in Active Galactic Nuclei (AGN)…

Tests of general relativity at the fourth post-Newtonian order
Poulami Dutta Roy, Sayantani Datta, K. G. Arun
The recently computed post-Newtonian (PN) gravitational-wave phasing up to 4.5PN order accounts for several novel physical effects in compact binary dynamics such as the {\it tail…

Impact of unmodeled eccentricity on the tidal deformability measurement and implications for gravitational wave physics inference
Poulami Dutta Roy, Pankaj Saini
With the expected large number of binary neutron star (BNS) observations through gravitational waves (GWs), third-generation GW detectors, Cosmic Explorer (CE) and Einstein Telesco…
