Measurements of radio emission induced by Ultra-high energy Cosmic rays with energies above 1 EeV with AERA — •Florian Briechle and Martin Erdmann — RWTH Aachen University, III. Physikalisches Institut A

Ultra-high energy cosmic rays induce extensive air showers emitting radiation in the radio regime which can be used to reconstruct their properties. The radio array AERA of the Pierre Auger Observatory is due to its large size of 17 km**2 able to achieve large event statistics. Incoming cosmic rays at high zenith angles are particularly interesting due to their large footprint on ground which can be measured in many stations. However, their reconstruction is challenging. In this talk a lateral distribution function for fitting the energy fluence on ground of these showers is presented with an emphasis on the energy reconstruction. This allows an energy estimation of the primary cosmic ray using only the information gathered from the radio emission.
