journal contribution
posted on 2023-05-21, 11:34 authored by Abbott, BP, Abbott, R, Karelle SiellezKarelle Siellez, Zweizig, JA transient gravitational-wave signal, GW150914, was identified in the twin Advanced LIGO detectors on 2015 September 2015 at 09:50:45 UTC. To assess the implications of this discovery, the detectors remained in operation with unchanged configurations over a period of 39 days around the time of the signal. At the detection statistic threshold corresponding to that observed for GW150914, our search of the 16 days of simultaneous two-detector observational data is estimated to have a false-alarm rate (FAR) of <4.9 x 10-6 yr-1, yielding a p-value for GW150914 of <2 x 10-7.
