"The DESI Survey and Galaxy Evolution: Lyman Alpha Emitters and the Andromeda Galaxy"

Abstract: The Dark Energy Spectroscopic Instrument has begun its 5-year mission to explore the universe both near and far and map out its expansion history. In addition to its primary cosmological goals, DESI will provide new insights into the formation and evolution of galaxies, as well as map out the dynamics of our Milky Way. I will describe the overall project and its data, and highlight two explorations: one on high-redshift galaxies; and the other on the Andromeda Galaxy, one of our most accessible astrophysical laboratories for investigating galaxy formation.
