Description
Ultra-high-energy cosmic rays are the highest energetic particles known - and yet their origin is still an open question. This is mainly because they are deflected by cosmic magnetic fields during their travel from the sources to Earth, so that their direction of arrival does not correspond to the direction of the source. At the Pierre Auger Observatory, several quantities of ultra-high-energy cosmic rays are measured, namely their energies, arrival directions, and their atmospheric penetration depth, an indicator for their charge. To learn more about the sources, this data can be compared to predictions of astrophysical models. In these models, the whole process from emission at the sources, interactions with magnetic fields and background photon fields, as well as the detection of Earth has to be taken into account. Through a fit to the data, quantities like the density and distribution of cosmic-ray sources can be constrained. This contribution will provide an overview over the latest results in the ongoing search for the sources of ultra-high-energy cosmic rays.
