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 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…
