My research explores the interstellar medium, the gas between the stars in our galaxy. Some of this gas is heated to millions of degrees by the most explosive events in the galaxy, supernova explosions. In order to estimate how supernova remnant bubbles affect parts of our galaxy and in order to study particular microphysical processes, I perform computer simulations. When tests of the theoretical and computational predictions require additional astronomical observations, I use X-ray and ultraviolet telescopes (mounted on satellites) to observe individual supernova remnant bubbles and the general interstellar medium.
