Abstract:

Gravitational wave (GW) echoes, the GWs reflected from the surface of an exotic compact object (ECO), may provide information about the Planck-scale structure near the horizon. Previous work on GW echoes is mostly done for non-rotating ECOs described by Schwarzschild metric. In more general cases, a theoretical model for GW echoes from spinning ECOs is of importance in the searches for echoes in LIGO/Virgo data. In this project, we derive the echo waveforms for a spinning ECO, incorporate them into current search pipelines, and study the stability of spinning ECOs.
