Constraints on upward-going air showers using the Pierre Auger Observatory data

open access: goldInternational Conference on Rebooting Computing, 2023
The fluorescence detector (FD) of the Pierre Auger Observatory is sensitive to upward-going air showers with energies above 10 17 eV. Given its operation time and wide field of view, the FD has the potential to support or constrain the “anomalous ...

Determining Electric Fields in Thunderclouds With the Radiotelescope LOFAR. [PDF]

open access: yesJ Geophys Res Atmos, 2020
Abstract An analysis is presented of electric fields in thunderclouds using a recently proposed method based on measuring radio emission from extensive air shower events during thunderstorm conditions. This method can be regarded as a tomography of thunderclouds using cosmic rays as probes. The data cover the period from December 2011 till August 2014.

Single source scenario describing the very end of the cosmic ray energy spectrum [PDF]

open access: yesEPJ Web of Conferences, 2023
The energy spectrum of cosmic rays is steeply falling with a suppression of the flux at the highest energies caused by energy losses during propagation or by reaching the maximum energy of cosmic accelerators.
