SCARAB: Studying Circumgalactic Absorbers Revealed Across ByCycle

My goal as a MSCA fellow is to obtain a clear picture of the extent, distribution, and enrichment of the circumgalactic medium (CGM) gas around galaxies, refine our understanding of how gas flows through it, and establish observational connections to the galaxies that host it in order to shed light on long-standing questions about the CGM's integral role in galaxy evolution. This research, based on an unprecedented new dataset from the 4MOST/ByCycle survey that increases available halo absorber sightlines by three orders of magnitude, has the potential to change our view of how galaxies work and will generate a legacy data set that astronomers will use long into the future. Working with Celine Peroux at the European Southern Observatory (ESO) in Germany, I will contribute my expertise in quasar absorption-line spectroscopy and the Milky Way CGM, and benefit by extending my existing knowledge about the CGM to higher redshifts while developing data science skills through management and statistical analysis of large data sets.
