The Undergraduate Research series is where we feature the research that you’re doing. If you are an undergraduate that took part in an REU or similar astro research project and would like to share this on Astrobites, please check out our submission page for more details. You can also share your more general research experience, find out more here.

Sean ClarkNorth Carolina State UniversityThis guest post was written by Sean Clark. Sean Clark is a senior in aerospace engineering at North Carolina State University. He conducted this research to supplement his pursuit of a minor in physics. This work was presented at the AAS 236th meeting and a manuscript currently in preparation. How much low-metallicity gas galaxies accrete onto their disk determines whether they can sustain star formation over long timescales, and therefore affects their evolutionary path. This accreted gas can stem from intergalactic sources, mergers with satellite galaxies and from gas feedback processes within the galaxy itself. This feedback process, known as the baryonic cycle, involves material being expelled by supernovae and the active galactic nucleus out to the galaxy halo or circumgalactic medium (CGM) before it is accreted back into the disk once it has cooled and ...
