Search for echoes on the edge of quantum black holes
Jahed Abedi
I perform a template-based search for stimulated emission of Hawking radiation (or Boltzmann echoes) by combining the gravitational wave data from 47 binary black hole merger event…

Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…

A gating-and-inpainting perspective on GW150914 ringdown overtone: understanding the data analysis systematics
Yi-Fan Wang, Collin D. Capano, Jahed Abedi +5
We revisit the recent debate on the evidence for an overtone in the black hole ringdown of GW150914 using an independent data-analysis pipeline. By gating and inpainting the data,…
