Exact Cancellation of Horizon Modes in Kerr Ringdown

Kei-ichiro Kubota, Yusuke Manita, Hayato Motohashi +1

Ringdown gravitational waves probe black hole spacetimes via quasinormal modes (QNMs). Recent studies have reported oscillatory features in QNM-filtered waveforms, and have led to…

Ringdown analysis of GW250114 with orthonormal modes

Motoki Suzuki, Kei-ichiro Kubota, Soichiro Morisaki +2

GW250114 is the loudest gravitational wave event to date observed by LIGO-Virgo-KAGRA Collaboration. Owing to its high signal-to-noise ratio (SNR), previous analyses based on quasi…
