Investigating the effect of hadronic models on IACT images
Benedetta Bruno, Rodrigo Guedes Lang, Luan Bonneau Arbeletche +2
The predictions of hadronic interaction models for cosmic-ray induced air showers contain inherent uncertainties due to limitations of available accelerator data. This leads to dif…

On gamma rays as predictors of UHECR flux in AGNs
Cainã de Oliveira, Rodrigo Guedes Lang, Pedro Batista
Active galactic nuclei (AGN) are among the main candidates for ultra-high-energy cosmic ray (UHECR) sources. However, while some theoretical and phenomenological works favor AGNs a…

High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S
F. Aharonian, F. Ait Benkhali, J. Aschersleben +144
Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…
