Description

How do cosmic rays shape the ecology of galaxies? Cosmic rays -- charged particles traveling through space at nearly the speed of light -- are an important constituent of galaxies, but we do not fully understand how they interact with galactic gas. This project will clarify that interaction by applying new computational techniques to predict emission from cosmic rays to observations from a new generation of Australian and international radio, gamma-ray, and neutrino telescopes. The improved understanding will in turn reveal the role of cosmic rays in shaping the formation and evolution of galaxies like our own Milky Way. This will have the cultural benefit of clarifying our cosmic origins, and will enhance Australian leadership of and science return from major international facilities.. Scheme: Discovery Projects.
