Research Interests:
I'm interested in how galactic interactions with warm halo gas affect galaxy evolution. I study the poorly understood warm ionized gas in the Magellanic System and in High Velocity Clouds.
Biography:
My dissertation concentrates on galactic interactions with warm halo gas. Halo gas interactions influence galactic evolution by fueling star formation and modifying metallicity. For this work, I use the Wisconsin Hα Mapper to study the faint, warm ionized gas. The Hα observations allow us to study the extent and large-scale velocity structure of the ionized gas, giving clues on the source(s) of ionization, the ionization fraction, and the mass of the ionized component. In addition, [SII] and [NII] studies probe the physical conditions of these regions, including temperature and metallicity.
The Magellanic System exhibits some of the nearest examples of interactions affecting galaxy...read more
