Up-going high energy showers in the fluorescence detector of the Pierre Auger Observatory — •Ioana Alexandra Caracas — Bergische Universität Wuppertal, Gaußstr. 20, 42119 Wuppertal
The Pierre Auger Observatory is performing a follow-up search of the recent ANITA observations of up-going cosmic ray like showers with energies around 0.1-1 EeV. Because of the vastly larger exposure of the fluorescence detector (FD) compared to ANITA, it is expected the current research will be able to either confirm or reject the recent observations. The 14 years of FD data are already taken and will be analyzed.
Simulations of up-going extensive air showers with elevation of more than ≈ 20 degrees above the horizon represent the first step in this search. These simulations will be used to reject the false positives and provide insight into the nature of these events. The extensive air showers are simulated using CORSIKA with primary energies in the range of 10 18 - 10 20 eV. Preliminary results of these simulations, including detector response simulations, will be presented and discussed.
