Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object

Elise M. Sänger, Soumen Roy, Michalis Agathos +16

On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…

Improved parametrized test of general relativity using the IMRPhenomX waveform family: Including higher harmonics and precession

Soumen Roy, Maria Haney, Geraint Pratten +2

When testing general relativity (GR) with gravitational wave observations, parametrized tests of deviations from the expected strong-field source dynamics are one of the most widel…
