Low evidence for ringdown overtone in GW150914 when marginalizing over time and sky location uncertainty
Alex Correia, Yi-Fan Wang, Julian Westerweck +1
Tests of the no-hair theorem using astrophysical black holes involve the detection of at least two quasi-normal modes (QNMs) in the gravitational wave emitted by a perturbed black…
Spectroscopy for asymmetric binary black hole mergers
Jahed Abedi, Collin D. Capano, Shilpa Kastha +5
We study Bayesian inference of black hole ringdown modes for simulated binary black hole signals. We consider to what extent different fundamental ringdown modes can be identified…
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,…
