Optimization of Radio Reconstruction for Inclined Air Showers with AERA at the Pierre Auger Observatory* — •Jelena Petereit for the Pierre Auger collaboration — Bergische Universität Wuppertal, Gaußstraße 20, Wuppertal, Germany
The Pierre Auger Observatory is the world’s largest cosmic ray observatory. Its Auger Engineering Radio Array (AERA) consists of more than 150 antenna stations that cover an area of about 17 km2 and is used to detect radio signals emitted by extensive air showers. These measurements are used to reconstruct properties of the primary cosmic rays inducing the air showers.
This talk describes the improvements that have been made on the AERA analysis with the Auger reconstruction framework. Using CoREAS simulations for measured event geometries, noise extracted from data can be added to a simulated pure signal. Various parameters for identifying noise dominated stations for the rejection in the geometry reconstruction, such as the time difference between the pure signal and the signal with noise, are examined and modified in order to improve the event reconstruction.
