The speaker will discuss two different projects with which he has been involved, with the common theme of doing experimental astrophysics in extreme environments, namely the South Pole and 1100 m underground down a salt mine. Astroparticle physics sits between cosmology, astronomy and particle physics. It studies the implications for the very large scale of our galaxy – studying sub-atomic particles and processes. The two projects which the speaker will discuss investigated the origin of high-energy gamma rays and searched for the elusive dark matter particle. The talk will focus primarily on doing experimental physics in extreme environments, with an overview of the science being undertaken.
