PHY418 - Particle Astrophysics
The LHC accelerates protons to kinetic energies of up to 7000 times their rest mass - a huge technological achievement. Yet, every second, over 500 million particles with energies greater than this collide with the Earth. Where do these particles come from, and how are they accelerated to these astonishing energies? These are, in fact, still open questions in astrophysics. In this module, we will look at the observational evidence for particle acceleration in astrophysical objects, the mechanisms available to accelerate particles, and some of the likely sources, including supernovae and supernova remnants, neutron stars, and active galaxies.
