Searching for new particles in dense astrophysical media
Katelin Schutz
McGill University

In this seminar, I will discuss how we can treat various astrophysical systems, including stars and the pre-recombination plasma of the primordial universe, as components of a particle physics experiment that exists ?for free? in Nature. In some cases, the observed properties of these systems provide particle physics constraints that are 10 orders of magnitude stronger than what can be achieved in a collider experiment. I will discuss how we can use existing experiments and observations to explore even more parameter space by exploiting several effects that were previously unknown, including the effects of magnetic fields.
