Biases in Ringdown Tests of General Relativity from Gravitational-Wave Microlensing
Sreelakshmi Mundakkal Dasan, Anuj Mishra, Apratim Ganguly
Gravitational-wave (GW) ringdown signals provide a powerful probe of the strong-field regime of general relativity (GR) through black hole spectroscopy and tests of the Kerr hypoth…
