The IceCube Collaboration (http://icecube.wisc.edu/) reports:
IceCube has performed a search for track-like muon neutrino events arriving from the direction of the FRB 190714 (ATel #12940) in a time window 200 seconds in duration centered on the burst time (2019-07-14 05:35:32.9 UTC to 2019-07-14 05:38:52.9 UTC), during which IceCube was collecting good quality data. Zero track-like events are found in spatial coincidence with FRB 190714 during this time period. Accordingly, the time-integrated muon-neutrino flux, multiplied by E^2, upper limit at the alert position assuming an E^-2 spectrum (E^2 dN/dE) at the 90% CL is 1.65 x 10^-4 TeV cm^-2 for this observation period. 90% of events IceCube would detect from a source at this declination with an E^-2 spectrum are between approximately 20 TeV and 25 PeV.
An additional search was performed to include the entire 24-hour time window centered on the burst time (2019-07-13 17:37:12.9 UTC to 2019-07-14 17:37:12.9 UTC). Zero track-like events are found in spatial coincidence with FRB 190714 during this time period, and the corresponding time-integrated muon-neutrino flux, multiplied by E^2, upper limit assuming an E^-2 spectrum (E^2 dN/dE) at the 90% CL is 1.67 x 10^-4 TeV cm^-2.
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.
