Using data from the IceCube detector, we have performed a follow-up analysis of the recently reported single bright neutrino from the ANTARES ATel #7987.
IceCube is a cubic-kilometer neutrino detector installed in the ice at the geographic South Pole primarily sensitive to astrophysical neutrinos in the TeV-PeV energy range. At the coordinates of the reported event, IceCube's neutrino event selection yields an effective area greater than 1 m^2 for neutrino energies above 100 TeV. An energy threshold of 10 TeV is chosen to remove the otherwise large background of atmospheric muons present for this declination. The median angular resolution for muon neutrinos is 0.4 degrees, with 88% contained within three degrees.
No neutrino candidate events were recorded within three degrees of the ANTARES event coordinates during a 10^5 s time-window centered on the ANTARES event time.
This yields an upper limit on the flux of 5.6 · 10^-6 · E^-2 GeV cm-2 s-1 assuming an unbroken E-2 power law spectrum from a point source.
