Multi-Messenger Astronomy

Some interesting developments in astroparticle physics are discussed, taking advantage of novel experimental approaches. Multi-messenger astronomy is likely to open new insights on the physics of the most violent events in the universe. Examples are taken using UHE cosmic rays, γ-ray bursts and the exploration of dark matter using high energy photons. A generic case involving the detection of gravitational waves and neutrinos from the next galactic supernova is worked out in more detail, emphasizing its implications in particle and stellar collapse physics.
