Developments and results in the context of the JEM-EUSO program obtained with the ESAF simulation and analysis framework

JEM-EUSO is an international program for the development of space-based Ultra-High Energy Cosmic Ray observatories. The program consists of a series of missions which are either under development or in the dat...

The energy spectrum of cosmic rays beyond the turn-down around \(\varvec{10^{17}}\)  eV as measured with the surface detector of the Pierre Auger Observatory

We present a measurement of the cosmic-ray spectrum above 100 PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750 m. An inflection of the spectrum is observed, ...

Final results of the LOPES radio interferometer for cosmic-ray air showers

LOPES, the LOFAR prototype station, was an antenna array for cosmic-ray air showers operating from 2003 to 2013 within the KASCADE-Grande experiment. Meanwhile, the analysis is finished and the data of air-sho...

Direct measurement of the muonic content of extensive air showers between \(\mathbf { 2\times 10^{17}}\) and \(\mathbf {2\times 10^{18}}~\)eV at the Pierre Auger Observatory

The hybrid design of the Pierre Auger Observatory allows for the measurement of the properties of extensive air showers initiated by ultra-high energy cosmic rays with unprecedented precision. By using an arra...

Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory

Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with ...
