The IceCube Collaboration (http://icecube.wisc.edu/) reports:
IceCube has performed a search for track-like muon neutrino events arriving from the position of TXS 0506+056 over the time window of one week (2018-11-27 00:00:00 UTC to 2018-12-04 00:00:00 UTC) motivated by recent MAGIC observations (http://www.astronomerstelegram.org/?read=12260). One track-like event is found in spatial coincidence with TXS 0506+056, consistent with the atmospheric background expectation, and resulting in a p-value of 1.0. Accordingly, we set a time-integrated muon-neutrino flux normalization upper limit of 4.12 x 10^-5 TeV cm^-2 at the 90% CL for this observation period, assuming an E^-2 spectrum in an approximate energy range of 1 TeV to 1 PeV (E^2 dN/dE).
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.
