Astroparticle physics: how the biggest objects in the Universe are infl uenced by its tiniest constituents

It may seem counterintuitive that astronomy, the study of incomprehensibly big things, could be in any way c onnected to particle physics—the study of the incomprehensibly small. Howev er, the field of astroparticle physics is a rich and fascinating discipline that reveals there are many deep connections between these two realms. In fact, many astronomical objects cannot be understood without knowledge of t he processes governing the behaviour of fundamental particles. And on the f lip side, studying the behaviours of things like stars and galaxies can giv e us unique insights into fundamental physics that we would never be able t o gain access to in mundane human-scale laboratory experiments. Astropartic le physics therefore deals with some of the largest outstanding questions t hat we still have about the universe, such as the nature of the elusive dar k matter, among other mysteries.
