| Opis: | We present a new energy transport code that models the time dependent and non-linear evolution
of spectra of cosmic-ray nuclei, their secondaries, and photon target fields. The software can inject
an arbitrary chemical composition including heavy elements up to iron nuclei. Energy losses and
secondary production due to interactions of cosmic ray nuclei, secondary mesons, leptons, or
gamma-rays with a target photon field are available for all relevant processes, e.g., photo-meson
production, photo disintegration, synchrotron radiation, Inverse Compton scattering, and more.
The resulting x-ray fluxes can be fed back into the simulation chain to correct the initial photon
targets, resulting in a non-linear treatment of the energy transport. The modular structure of the
code facilitates simple extension of interaction or target field models.
We will show how the software can be used to improve predictions of observables in various
astrophysical sources such as jetted active galactic nuclei (AGN). Since the software can model
the propagation of heavy ultrahigh-energy cosmic rays inside the source it can precisely predict
the chemical composition at the source. This will also refine predictions of neutrino emissions
–– they strongly depend on the chemical composition. This helps in the future to optimize the
selection and analyses of data from the IceCube neutrino observatory with the aim to enhance the
sensitivity of IceCube and reduce the number of trial factors. |
