Inferring host environment properties and gravitational-wave decay time from the eccentricity measurement of dynamically captured binaries
A. Vincent Paul, Parthapratim Mahapatra, Marc Favata +1
Dynamical capture in dense stellar environments is a promising channel for producing eccentric compact binary mergers. Although there have been no confident detections of eccentric…
The High-Mass-Ratio Challenge in Gravitational Waveform Modelling
Parthapratim Mahapatra, Jonathan E. Thompson, Edward Fauchon-Jones +1
Binary black hole (BBH) mergers detected via gravitational waves are addressing key open questions in astrophysics, cosmology, and fundamental physics. Our scientific conclusions r…
Confronting general relativity with principal component analysis: Simulations and results from GWTC-3 events
Parthapratim Mahapatra, Sayantani Datta, Ish Gupta +10
We present a comprehensive assessment of multiparameter tests of general relativity (GR) in the inspiral regime of compact binary coalescences using principal component analysis (P…
Possible binary neutron star merger history of the primary of GW230529
Parthapratim Mahapatra, Debatri Chattopadhyay, Anuradha Gupta +4
Black holes (BHs) with masses between , produced by a binary neutron star (BNS) merger, can further pair up with a neutron star or BH and merge again within a Hu…
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)…
Reconstructing the Genealogy of LIGO-Virgo Black Holes
Parthapratim Mahapatra, Debatri Chattopadhyay, Anuradha Gupta +4
We propose a Bayesian inference framework to predict the merger history of LIGO-Virgo binary black holes (BHs), whose binary components may have undergone hierarchical mergers in t…
Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
Multiparameter multipolar test of general relativity with gravitational waves
Parthapratim Mahapatra, Shilpa Kastha, Anuradha Gupta +2
Amplitude and phase of the gravitational waveform from compact binary systems can be decomposed in terms of their mass- and current-type multipole moments. In a modified theory of…
Parametrized multipolar gravitational waveforms for testing general relativity: Amplitude corrections up to 2PN order
Parthapratim Mahapatra, Shilpa Kastha
A parametrized multipolar gravitational wave phasing within multipolar post-Minkowskian and post-Newtonian formalism was developed in earlier works [S. Kastha et al., PRD 98, 12403…
