Core-collapse supernovae as possible counterparts of IceCube neutrino multiplets — •Nora Linn Strotjohann1, Markus Voge2, Marek Kowalski1, and Anna Franckowiak1 for the IceCube collaboration — 1Desy Zeuthen, Platanenallee 6, 15738 Zeuthen, Germany — 2Physikalisches Institut, Nussallee 12, 53115 Bonn, Germany
While an astrophysical neutrino flux has been detected by the IceCube Neutrino Observatory its sources remain so far unidentified. IceCube's Optical Follow-up Program is designed to search for the counterparts of neutrino multiplets using the full energy range of the IceCube detector down to 100 GeV. Two or more muon neutrinos arriving from the same direction within few seconds can trigger follow-up observations with optical and X-ray telescopes. Since 2010 the Palomar Transient Factory has followed up about 40 such neutrino alerts and detected several supernovae. Many of the detections are however likely random coincidences. In this talk I will describe our search for supernovae and the prospects of identifying a supernova as a source of high-energy neutrinos.
