Abstract

Chemical elements heavier than helium—commonly referred to as “metals” in astrophysics—are produced in stars and distributed throughout the Universe via outflows and stellar winds. Understanding metal enrichment in the early Universe is key to understanding galaxy evolution. I will present new observations of the circumgalactic and intergalactic medium at high redshift, tracing metals to study how they escape galaxies and how they relate to the history of cosmic star formation.
