Recent developments from the Auger Engineering Radio Array (AERA) * — •Marvin Gottowik — Bergische Universität Wuppertal, Gaußstraße 20, 42119 Wuppertal
The Auger Engineering Radio Array (AERA) is designed to measure the radio emission of extensive air showers initiated by cosmic rays above an energy of 1017 eV. AERA is an extension of the Pierre Auger Observatory located in Mendoza, Argentina. It is operated n coincidence with the other detectors of the observatory. The 153 autonomous radio antenna stations are distributed over an area of 17 km2 on a grid with a spacing ranging from 150 - 750 m. Each antenna station comprises two dipole antennas sensitive to frequencies of 30 - 80 MHz. Data taking started in 2011.
Special emphasis is put on the detection of inclined air showers, where the radio emission footprint extends over several square kilometers. This motivates the upcoming radio extension of the Pierre Auger Observatory with a radio antenna mounted to each station of the surface detector array. With an optimized radio event reconstruction dedicated to inclined air showers and a possible combination of radio and particle data an independent mass scale and an absolute energy calibration from first principles can be achieved. In this talk an overview of the current status of the experiment and the latest scientific results is given.
