Galaxies and gas at the interface of theory and data

I mainly work on topics in galaxy evolution, using the heavy elements as tracer particles of the flows of gas into, within, and out of galaxies. I am particularly interested in the interplay between galaxies and the intergalactic and circumgalactic media, with a focus on how star formation and stellar deaths affect galaxies and their surroundings.

I use different theoretical models (empirical, semi-empirical, analytic, semi-analytic, hydrodynamic simulations, ...) to both extract from the data as much information as possible and to get at the underlying physical processes giving rise to the observations. The above image (courtesy of Ben Oppenheimer) shows gas (color coded by temperature, blue = cold, red = hot) blowing out of galaxies in "superwinds" into the intergalactic medium.
