Welcome! I study the evolution of galaxies by examining their circumgalactic medium (CGM), a gaseous reservoir of dynamically complex, multi-phase, metal enriched gas that surrounds galaxies. The gas is observed in absorption using the technique of quasar absorption lines. When a quasar resides behind a galaxy, the GCM gas imprints absorption patterns in the spectrum of the quasar. From these we measure the gas temperature, metallicity, kinematics, etc. We aim to learn about the role of the cycle of gas (called the baryon cycle) in governing the formation and evolution of galaxies. |
