Center for Astrophysics Research and Technologies Seminar Series
Revelations From The Balmer-dominated Supernova Remnants in the LMC
Presented by Luke Hovey, LANL
Supernova remnants make ideal astrophysical laboratories for studying a host of physical/astrophysical phenomena. Remnants in the Large Magellanic Cloud are of particular importance for studying the dynamics of shockwaves and ejecta since the distance to the LMC has been measured with much greater accuracy then the distances to the remnants in our own galaxy. I will be highlighting my work on the two youngest Ia remnants in the LMC that are of Ia origin. My work has concentrated on measuring the shock speeds of these remnants through HST proper motions with narrow-band H$alpha$ imaging. These measurements aided me in constraining the age, dynamical state, ambient medium densities, electron-ion temperatures, Cosmic-ray acceleration efficiencies, and the progenitor systems of these remnants. I look forward to sharing with you all that I have learned about these unique supernova remnants.
