CRPropa 3.0 – a Public Framework for Propagating UHE Cosmic Rays through Galactic and Extragalactic Space* — Rafael Alves Batista1, Martin Erdmann2, Carmelo Evoli1, Karl-Heinz Kampert3, •Daniel Kuempel2, Gero Müller2, Peter Schiffer1, Guenter Sigl1, Arjen van Vliet1, David Walz2, and Tobias Winchen2 — 1II.

The interpretation of experimental data of ultra-high energy cosmic rays (UHECRs) above 1017 eV is still under controversial debate. The development and improvement of numerical tools to propagate UHECRs in galactic and extragalactic space is a crucial ingredient to interpret data and to draw conclusions on astrophysical parameters. In this contribution the next major release of the publicly available code CRPropa (3.0) is presented. It reflects a complete redesign of the code structure to facilitate high performance computing and comprises new physical features such as an interface for galactic propagation using lensing techniques and inclusion of cosmological effects in a three-dimensional environment. The performance is benchmarked and first applications are presented.
