4. Radio Detection of Air Showers at the Pierre Auger Observatory

Frank Schröder (Karlsruhe Institute of Technology (KIT))

3/24/20, 12:30 PM

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...

10. Radio detection of air showers with OVRO-LWA

Anna Nelles

3/24/20, 2:30 PM

The OVRO-LWA is a distributed radio telescope in California. Due to its unique technical set-up, it was used to detect air showers exclusively in self-trigger mode. I will discuss how the OVRO-LWA can be used to develop self-triggering algorithms that may be used for other air shower arrays.

12. Tunka Radio Extension

Dmitriy Kostunin (DESY)

I give an overview of Tunka-Rex, its achievements and future plans

13. The development of methods for implementing a self-trigger

Yulia Kazarina (API ISU)

9. Radio detection of neutrinos with RNO-G

Anna Nelles

3/26/20, 11:15 AM

The Radio Neutrino Observatory (RNO-G) will start construction in 2020 in Greenland. It will target neutrinos above 10 PeV. It is built on experience with the pathfinders ARA and ARIANNA and the successes of air shower arrays.
I will summarize the design and capabilities.

19. Development of efficiency models for cosmic-ray radio instruments

Mr Vladimir Lenok (Karlsruhe Institute of Technology)

3/26/20, 12:00 PM

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.

3. Tien Shan extensive air shower array and its radio receiver subsystem

Alexander Shepetov (P.N.Lebedev Physical Institute)

3/26/20, 12:30 PM

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...

20. Autoencoder for Tunka-Rex

Pavel Bezyazeekov

Reconstruction of air-shower parameters by radio data puts high demands on the purity of measured signal and signal-to-noise ratio, which is not always possible in real conditions. Measurements suffers from RFI related to man-made, ionospheric and other sources. For lowering the threshold on amplitude and energy of primary particle as well as increasing statistics we apply autoencoder network...
