5. High-energy particles from astrophysical transients

Decisive advances in the understanding of explosive transients have been made possible by the development of multi-messenger astronomy and time-domain astronomy. However, the origin of high-energy (HE) to ultra-high-energy (UHE) cosmic rays and neutrinos remain unclear. Deciding between the various source candidates requires a precise modeling of the propagation, acceleration and interactions...

1. Efficient UHECR simulations with PriNCe and what they taught us so far

Xavier Rodrigues (Ruhr University Bochum)

In this talk I will introduce PriNCe (Heinze et al 2019) as a novel open-source Python software for UHECR propagation. The computational efficiency of PriNCe allows the user to perform vast scans of the source parameters, the emitted spectral shape, and the mass composition. I then discuss recent applications of the code, such as the first joint fit to Auger and Telescope Array (TA) spectral...

6. Gamma-ray attenuation from extragalactic background light in the Fermi and CTA era

Alberto Saldana-Lopez (University of Geneva)

The diffuse extragalactic background light (EBL) is formed by ultraviolet (UV), optical, and infrared (IR) photons mainly produced by star formation processes over the history of the Universe and contains essential information about galaxy evolution and cosmology. The EBL also attenuates gamma-ray fluxes that travel cosmological distances through pair-production interactions, leaving a...
