    Galaxy evolution

    Bryan Terrazas is studying the evolution of galaxies with masses similar to that of the Milky Way by comparing and analyzing computational simulations. The goal is to better undertand what characteristics of high-redshift galaxies can be observed in order to identify progenitors of a subset of galaxies at the current epoch. He will explore their merger histories, gas accretion rates, star formation rates, as well as their eventual formation into either quiescent or star-forming galaxies in order to understand how these mechanisms affect the resulting progenitor galaxy population. An understanding of the sources of uncertainty with regard to growth histories will help clarify how to improve the agreement between models and observations. By looking at the evolutionary histories of Milky Way-mass galaxies, Terrazas hopes to establish a physical interpretation of observed properties for an important subset of the galaxy population, improving our understanding of how galaxies evolve through cosmic time.
