Testing general relativity using higher-order modes of gravitational waves from binary black holes
Anna Puecher, Chinmay Kalaghatgi, Soumen Roy +4
Recently, strong evidence was found for the presence of higher-order modes in the gravitational wave signals GW190412 and GW190814, which originated from compact binary coalescence…
Modeling the postmerger gravitational wave signal and extracting binary properties from future binary neutron star detections
Ka Wa Tsang, Tim Dietrich, Chris Van Den Broeck
Gravitational wave astronomy has established its role in measuring the equation of state governing cold supranuclear matter. To date and in the near future, gravitational wave meas…
A morphology-independent search for gravitational wave echoes in data from the first and second observing runs of Advanced LIGO and Advanced Virgo
Ka Wa Tsang, Archisman Ghosh, Anuradha Samajdar +4
Gravitational wave echoes have been proposed as a smoking-gun signature of exotic compact objects with near-horizon structure. Recently there have been observational claims that ec…
Testing the multipole structure of compact binaries using gravitational wave observations
Shilpa Kastha, Anuradha Gupta, K. G. Arun +2
We propose a novel method to test the consistency of the multipole moments of compact binary systems with the predictions of General Relativity (GR). The multipole moments of a com…
