LIGO/Virgo S190930t: Upper limits from IceCube neutrino searches
Abstract
Searches [1,2] for track-like muon neutrino events detected by IceCube consistent with the sky localization of gravitational-wave candidate S190930t in a time range of 1000 seconds [3] centered on the alert event time (2019-09-30 14:25:47.685 UTC to 2019-09-30 14:42:27.685 UTC) have been performed. During this time period IceCube was collecting good quality data. No significant track-like events are found in spatial coincidence of S190930t calculated from the map circulated in the 2-Initial notice. IceCube's sensitivity assuming an E^-2 spectrum (E^2 dN/dE) to neutrino point sources within the locations spanned by the 90% spatial containment of S190930t ranges from 0.029 to 1.150 GeV cm^-2 in a 1000 second time window. The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.
