CRPropa 3.2 — an advanced framework for high-energy particle propagation in extragalactic and galactic spaces — •Julien Dörner for the CRPropa collaboration — Theoretische Physik IV, Ruhr University Bochum, Bochum, Germany — RAPP-Center at Ruhr University Bochum, Bochum, Germany

The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and neutrino observatories. At the dawn of the multimessenger era, the interpretation of these observations within a consistent framework is important to elucidate the open questions in this field. CRPropa 3.2 is a Monte Carlo code for multimessenger simulations of high-energy particles and their secondaries. With this new version, the framework is now extended to more than extragalactic propagation opening up the possibility to more astrophysical applications, like Galactic cosmic-ray and local source modeling.

In this talk, we will show some of these new aspects that can be applied with CRPropa 3.2. It will include simulations of high-energy particles in diffusion dominated domains and self-consistent, fast modelling of electromagnetic cascades and interactions with customized photon fields. With the new CRPropa 3.2 version several technical updates and improvements were implemented, which will be presented in the talk.
