Impact of uncertainties in the detector geometry of IceCube on event reconstruction — •Lilly Peters, Frederic Jonske, Martin Rongen, Jöran Stettner, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen

Neutrinos travel through the universe nearly undisturbed, keep their directional information and provide the possibility to study the unknown sources of high-energy cosmic rays. In 2017, the IceCube Neutrino Observatory has identified, for the first time, a potential astrophysical neutrino source, the Blazar TXS 0506+056. The ability to reliably trace back a neutrino to an astrophysical source requires a precisely reconstructed direction. One source of systematic uncertainties is the actual position of the optical sensors of the detector. Those positions can be estimated from calibration light sources and deployment data taken during the construction of the detector. In this talk, the influence of geometrical uncertainties of the IceCube detector array on directional reconstructions of high-energy neutrinos will be analyzed.
