This is a talk given at lunch time, usually in the conference room at noon.
The search for dark matter offers the possibility for rich new physics that deepens our understanding of the Universe.
There is a diversity in the types of galaxies that exist, and the Milky Way is but one of them. Yet, studying the Milky Way’s stellar populations, their detailed chemical abundances, kinematics, and other properties, provides us with an unparalleled view of galaxy formation.
In this talk, I will present our new Lyman-alpha observations focusing on the circumgalactic medium of z~2 star-forming galaxies, in both absorption and emission using Keck-LRIS and KCWI. For absorption, we use the spectra of ~3000 galaxies from the Keck Baryonic Structure Survey (KBSS) to assem
