The violent Universe still defies us, as the sources of ultra-high-energy cosmic rays remain unknown. Yet we have drastically increased the amount of information at very high energies in the last 5 years, with combined observations of cosmic rays, gamma rays, neutrinos, and gravitational waves. We will identify in this talk the multi-messenger data that can be relevant to solve this...

We discuss the possibility that ultra-high energy cosmic rays (UHECR) may be accelerated by shocks in the lobes of radio galaxies. Acceleration at the termination shocks of jets is problematic because relativistic shocks are poor accelerators to high energy. We show that non-relativistic shocks with suitable Hillas parameters occur in plasma streams flowing out of the jet termination regions...

I will present an overview of recent developments in numerical modelling of CR transport in our Galaxy. Corresponding numerical models aim at reproducing CR spectra and also diffuse gamma-ray emission from the Galaxy. For these numerical models we witness a transition from two-dimensional azimuthally symmetric models to those that use a more realistic description of our Galaxy. Focusing on...

Antimatter cosmic rays have become a fashionable tool to probe for the presence of dark matter particles in the Milky Way. Should these species exist, they would annihilate or decay, hence producing positrons and anti-nuclei which would distort the conventional signals expected at the Earth. But are these backgrounds well known? There’s the rub.
Regardless of the dark matter problem,...
