Subject
LIGO/VIRGO S190425z: IceCube Neutrino Search

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 S190425z in a time range of 1000
seconds centered on the alert event time (2019-04-25 08:09:45.000 UTC to 2019-04-25 08:26:25.000 UTC)
during which IceCube was collecting good quality data.
No track-like events are found in spatial coincidence with the 90% spatial containment of S190425z calculated from the map
circulated in the preliminary notice.

IceCube's sensitivity to point sources within the location spanned by the 90% spatial containment of S190425z ranges from
0.029 to 1.019 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.
The IceCube realtime alert point of contact can be reached at roc@icecube.wisc.edu
