Feb 20 3:00 p.m. RLM 5.104	SPECIAL COLLOQUIUM Sanchayeeta Borthakur Johns Hopkins University	Role of Baryon Flows in Galaxy Evolution: Hidden Pathways Connecting Galaxies to the Cosmic Web Galaxies are not isolated. They constantly exchange matter and energy with their surroundings. Galaxy growth and subsequent star formation is maintained by accretion of gas. In turn, young stars produce vast amounts of energy that may ionize gas in the cosmic web as well as spew out metals in the intergalactic medium (IGM). In this talk, I will discuss the advances we have made in understanding the physics behind baryon flows by studying the properties of the circumgalactic medium (CGM). The CGM is the vast reservoir of faint tenuous gas that extends from the edge of the disks of galaxies out to their virial radii. Therefore, the CGM holds crucial clues to understanding the various inflow and outflow processes. I will present observational evidence that suggests of the pathways via which galaxies acquire gas, condense it into their interstellar medium, form stars, and finally, release matter and energy back into the cosmic web through their CGM. close
