TITLE: GCN CIRCULAR NUMBER: 24103 SUBJECT: LIGO-Virgo S190412m: Search for neutrino counterparts with IceCube DATE: 19/04/12 11:35:09 GMT FROM: Erik Blaufuss at U. Maryland/IceCube The IceCube Collaboration (http://icecube.wisc.edu/) reports: IceCube has performed a search for track-like muon neutrino events consistent with the sky localization of S190412m in a time range of 1000 seconds centered on the alert event time (2019-04-12 05:22:24.166 UTC to 2019-04-12 05:39:04.166 UTC) during which IceCube was collecting good quality data. No track-like events are found in spatial coincidence with the 90% spatial containment of S190412A calculated from the map circulated in the initial notice. IceCube's sensitivity to point sources within the location spanned by the 90% spatial containment of S190412m ranges from 0.029 to 0.048 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.
