Search for High Energy Astrophysical Tau Neutrinos using IceCube Data — •Maximilian Meier, Thorben Menne, Mathis Börner, Mirco Hünnefeld, Tobias Hoinka, Jan Soedingrekso, and Alexander Sandrock for the IceCube collaboration — TU Dortmund

The IceCube Neutrino Observatory at the South Pole is a Cherenkov detector designed to measure astrophysical neutrinos of all flavors. High energy tau neutrinos interacting inside the detector produce two cascades separated by the tau lepton decay length. At energies above 100 TeV the spatial separation can be resolved within the waveform of one IceCube optical module and identified as a double pulse signature. This work aims to select events with a cascade-like topology that contain at least one double pulse signature. This talk will give an overview over the current status of this analysis and its prospects.
