"Cosmic Rays & Multi-Messenger Opportunities in Starbursts"

Supernovae in regions of intense star-formation naturally generate high number densities of cosmic rays, with energies up to a few PeV in the most extreme systems. As such, starburst galaxies are of particular interest for studying the both the fundamental properties of cosmic rays and mechanisms for feedback in galaxies. In this case, studying starbursts requires both radio and gamma-ray observations as probes of their cosmic ray populations, as well as a detailed understanding of the interstellar medium via millimeter-radio, infrared, and optical observations. In this talk, I will present an overview of cosmic ray interaction models for starburst galaxies and of the role of cosmic rays in galaxy evolution.
