Seasonal Variations of the unfolded Atmospheric Neutrino Energy Spectrum with IceCube — •Karolin Hymon1,2, Tim Ruhe1, and Julia Tjus2 for the IceCube collaboration — 1TU Dortmund — 2Ruhr-Universität Bochum
The IceCube Neutrino Observatory is a detector array at the South Pole with the central aim of studying high energy neutrinos of astrophysical origin. The majority of the detected neutrinos, however, are atmospheric neutrinos, caused by cosmic ray interactions in the atmosphere. The rate of atmospheric neutrinos undergoes a seasonal variation with indications that the rate changes with the temperature in the stratosphere. Possible implication of this variation on the shape of the atmospheric neutrino spectrum have not been studied so far. This talk will focus on the investigation of possible shape changes of the atmospheric neutrino spectrum, which will be analyzed using the Dortmund Spectrum Estimation Algorithm (DSEA).
