RESEARCH STATEMENT: Through ultra-violet, intra-red and optical observations of type Ia supernovae, Dr. Milne is working towards the goal of understanding the nature of supernova explosions. As part of this work, he studies the cosmological utilization of this type of supernova, studying the amount of dark energy in the universe. A different research goal is to determine whether supernovae produce the bulk of Galactic positrons, seen in positron annihilation radiation, and if not, determining what does produce those positrons. Towards better studying supernovae and other transients with Steward Observatory telescopes, Dr. Milne is working on automation of smaller telescopes and on data reduction pipelines to handl large volumes of data with minimal human effort.
