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…
