The Pierre Auger Observatory in Argentina features the largest antenna array for air-shower detection, the Auger Engineering Radio Array (AERA). AERA consists of 153 antenna stations over 17 km$^2$, detecting air showers in the frequency band of 30-80 MHz. With AERA, the collaboration achieved key results, such as an absolute measurement of the radiation energy of the radio signal, which is...
I give an overview of Tunka-Rex, its achievements and future plans
Estimation of the efficiency is one of the crucial components for a comprehensive study of the cosmic rays with sparse radio-arrays. The direct estimation of this quantity with the Monte-Carlo approach is computationally demanding. Thus, we develop models for efficiency estimation based on the parametrizations of the radiation footprint. The details and recent updates of this work will be presented.
We consider the current status of the Tien Shan complex cosmic ray installation aimed for investigation of the 3-100 PeV extensive air showers (EAS). Together with a spatially distributed detector system of the charged EAS particles this installation includes also the hadron, muon, neutron, and gamma ray detectors which permit to create the complete picture of EAS development in each detected...
