The Auger Engineering Radio Array (AERA) is an array of $153$ radio antennas spanning an area of $17$ km$^2$, currently the largest of its kind, that probes the nature of ultra-high energy cosmic rays at energies around the transition from Galactic to extra-galactic origin. It measures the MHz radio emission of extensive air showers produced by cosmic rays hitting our atmosphere. The elemental...
We present the results of a new cosmic ray composition analysis above $10^{16.8}$ eV, based on measurements of the depth of air shower maximum $X_{\rm max}$ using the LOFAR radio telescope.
The reconstruction is done by simulating the radio signal for an ensemble of showers using Corsika and CoREAS.
The radio footprints on the ground are fitted to the measured radio data, yielding an...
The current generation of air shower radio arrays has demonstrated that the atmospheric depth of the shower maximum Xmax can be reconstructed with high accuracy. These experiments are now contributing to mass composition studies in the energy range where a transition from galactic to extragalactic cosmic-ray sources is expected. However, we are still far away from an unambiguous interpretation...
A first measurement of the muon content of an air shower using hybrid radio and particle detection is presented. For inclined air showers with zenith angles above 60°, the water-Cherenkov detector (WCD) of the Pierre Auger Observatory performs an almost pure measurement of the muonic component, whereas the Auger Engineering Radio Array (AERA) allows reconstructing the electromagnetic energy...
