How do cosmic rays shape the ecology of galaxies?

One of the oldest and most basic questions asked by all human cultures is "where did we come from?" In Australia today, this question drives public interest in astronomy and inspires new generations to pursue studies in science and engineering. This project will help answer a part of that question, by revealing the part in this origin story played by the mysterious particles known as cosmic rays -- particles that zip through space at nearly the speed of light, filling every part of our galaxy. The answers we obtain will be of broad interest to the public, and we will publicise them through venues such as The Conversation and other science magazines, and lectures aimed at the public. The process of obtaining the these answers will also provide training in fundamental research techniques that will prepare students for careers in a wide range of private- and public-sector professions that r
