Description
Solving the question of the origin of ultra-high energy cosmic rays
(UHECR) requires the development of detailed simulation tools in order
to interpret the experimental data and draw conclusions on the UHECR
universe. CRPropa is a public Monte Carlo code for the galactic and
extragalactic propagation of cosmic ray nuclei above $\sim 10^{17}$ eV, as well
as their photon and neutrino secondaries. In this contribution the new
algorithms and features of CRPropa 3, the next major release, are
presented.
CRPropa 3 introduces time-dependent scenarios to include cosmic
evolution in the presence of cosmic ray deflections in magnetic
fields.
The usage of high resolution magnetic fields is facilitated by shared
memory parallelism, modulated fields and fields with heterogeneous
resolution.
Galactic propagation is enabled through the implementation of galactic
magnetic field models, as well as an efficient forward propagation
technique through transformation matrices.
To make use of the large Python ecosystem in astrophysics, CRPropa 3
can be steered and extended in Python.
