Title: Search for minute-long neutrino sources with the IceCube detector
Abstract: IceCube has detected a diffuse astrophysical neutrino flux (at energies from 10 TeV to 10 PeV) and a flaring blazar was identified as a likely extragalactic neutrino source. However, bright blazars cannot account for the complete observed neutrino flux. In this talk, I will introduce IceCube's realtime optical and X-ray follow-up program which is triggered by 2 or more neutrinos arriving within 100s. No likely neutrino sources were identified by the program and it therefore provides generic constraints on the neutrino emission of short-lived transients such as GRBs, choked-jet SNe or binary neutron star mergers.
