Initial Size Distribution of the Galactic Globular Cluster System

Jihye Shin, Sungsoo Kim, Suk-Jin Yoon +1

Despite the importance of their size evolution in understanding the dynamical evolution of globular clusters (GCs) of the Milky Way, studies are rare that focus specifically on thi…

Star Formation Histories of Globular Clusters with Multiple Populations. I. ω Cen, M22, and NGC 1851

Seok-Joo Joo, Young-Wook Lee

There is increasing evidence that some massive globular clusters (GCs) host multiple stellar populations having different heavy element abundances enriched by supernovae. They usua…

An Old Supernova Remnant within an HII Complex at l {\approx} 173{\circ}: FVW 172.8+1.5

Ji-hyun Kang, Bon-Chul Koo, Chris Salter

We present the results of HI 21-cm line observations to explore the nature of the high-velocity (HV) HI gas at l ~ 173{\circ} . In low-resolution Hi surveys this HV gas appears as…
