Measuring photon-induced air showers with the AugerPrime Radio Detector — •Jannis Pawlowsky for the Pierre-Auger collaboration — Bergische Universität Wuppertal, Gaußstraße 20, 42119 Wuppertal, Germany

The AugerPrime upgrade represents a significant enhancement in the capability of the Pierre Auger Observatory to detect air showers. Central to this advancement is the installation of a radio antenna atop each existing Surface Detector (SD) station, constituting the Radio Detector (RD). RD enhances the sensitivity of the SD to the electromagnetic component of air showers. Hence, the new detector presents an opportunity for the discovery of rare particles such as ultra-high-energy photons.

This presentation focuses on the detection and reconstruction of photon-induced air showers at the highest energies. The radio trigger designed for the detection of photon events will be outlined and the trigger efficiency and reconstruction accuracy in simulation studies will be discussed. The presentation will conclude by summarizing the effectiveness and discrimination power of the new detector component.
