Cosmic Ecosystems
Details
Abstract:
While the pictures we see of galaxies appear as unchanging snapshots, we believe that they are vibrant ecosystems of stellar life. In this talk, I will describe how stars live and die in galaxies, with a particular focus on how stars are connected to the gas and dust inside a galaxy. We will explore the new understanding that we have gained from recent surveys of the nearest galaxies. These observations imply that, on cosmic timescales, galaxies are rapidly changing with their massive stars reshaping their interiors and charting a course for their future evolution.
Bio:
Erik Rosolowsky is a Professor of Physics and Astronomy at the University of Alberta. There, he teaches physics and astronomy, and he works with students in his research group to use telescope observations of the nearest galaxies to understand how those galaxies evolve.
