Hybrid Universality Model Development and Air Shower Reconstruction for the Pierre Auger Observatory

Hulsman, Johannes

Abstract (englisch):
Cosmic rays have been studied for more than 100 years, providing valuable information on the measured spectrum and theories to particle propagation and interaction. Potential sources, which could also serve possible acceleration mechanisms, include active galactic nuclei, gamma-ray bursts and supernova shock fronts. Due to our increased understanding of cosmic ray physics and technological improvements on a detector level, measurements have progressed towards even higher energies than before. To understand their origin, it is pertinent to understand their mass composition, energy spectrum and arrival direction. Laboratory-based particle accelerators and low energy cosmic ray experiments have elucidated our understanding of particle interaction, providing insight on possible acceleration and propagation models. However, ultra-high cosmic rays at $10^{20}$ eV are significantly above the highest energies achievable by the LHC (about two orders of magnitude between the center-of-mass energies). They are also very rare; with an incident flux of 1 particle per $km^{2}$ per century at $10^{20}$ eV. Accelerator-based models can be extrapolated to the highest energies. ... mehr
