| 요약 | The gaseous halo surrounding a galaxy disk is often referred to as the circum-galactic medium (CGM). The boundary of the CGM is loosely defined as the virial radius of the galaxy. Recent observations and simulations have shown that the CGM is ma |
| 요약 | Observations of the MW's CGM are unavoidably contaminated by foreground gas since we reside in the MW's disk. Conventionally, a velocity cut at |upsilonLSR| ~ 100 km s --1 is used as a proxy for distance, with low-velocity (| upsilonLSR| < 100 k |
| 요약 | I further study how baryons are cycled between the disk and CGM by observing gas accretion in M33. Using HST/COS to observe seven UV-bright stars in M33's disk, I find that there is a layer of metal-enriched inflow moving towards M33 at a rate o |
