Reconstruction of Events from the Radio Array AERA using a Spherical Shower Shape — •Lars Mohrmann, Martin Erdmann, and Stefan Fliescher — RWTH Aachen University, III. Physikalisches Institut A

The first phase of the Auger Engineering Radio Array (AERA) is in operation at the southern site of the Pierre Auger Observatory. It consists of 24 LPDA antennas and is designed to measure cosmic ray induced air showers by the detection of the radio pulse emitted during the shower development. The shape of the radio pulse is expected to exhibit a curvature.

Assuming the incoming radio signal to be a spherical wave, its 3-dimensional space point can be reconstructed using the arrival times of the radio pulse if observed at at least four antenna positions. We analyze the first AERA data using this method and search for nearby radio wave point sources and cosmic ray induced air showers.
