Professor Lindsay Glesener is a faculty member at the Minnesota Institute for Astrophysics on the Twin Cities campus. Her introduction: I am an astrophysicist examining the Sun, concentrating on the Sun’s remarkable capabilities for accelerating particles. Solar flares and coronal mass ejections transform huge amounts of energy from magnetic fields into kinetic energy through processes that are not yet understood. We attempt to evaluate and explain these phenomena by examining the high-energy emission from flares, all the way from large eruptive flares down to small, prevalent, unresolved ones. My main investigative tools are ultraviolet and X-ray data. I also work on the development of new instruments for high-energy exploration of the Sun, with an emphasis on X-ray sensors.
