A New Metal-poor Globular Cluster and Resolved Stars in the Outer Disk of the Black Eye Galaxy M64: Implication for the Origin of the Type III Disk Break
Jisu Kang, Yoo Jung Kim, Myung Gyoon Lee +1
M64 is a nearby spiral galaxy with a Type III anti-truncation component. To trace the origin of the Type III component, we present Hubble Space Telescope/Advanced Camera for Survey…
The Nature of Ultra-diffuse Galaxies in Distant Massive Galaxy Clusters: Abell 370 in the Hubble Frontier Fields
Jeong Hwan Lee, Jisu Kang, Myung Gyoon Lee +1
We report the discovery of ultra-diffuse galaxies (UDGs) in Abell 370 (). We find 46 UDGs in Abell 370 from the images of the Hubble Frontier Fields (HFF). Most UDGs are l…
Star Clusters in the Elliptical Galaxy NGC 4589 Hosting a Calcium-rich SN Ib (SN 2005CZ)
Myung Gyoon Lee, In Sung Jang, Jisu Kang
_NGC 4589, a bright E2 merger-remnant galaxy, hosts the peculiar fast and faint calcium-rich Type Ib supernova (SN) SN 2005cz. The progenitor of Ca-rich SNe Ib has been controversi…
Detection of a Large Population of Ultra Diffuse Galaxies in Massive Galaxy Clusters: Abell S1063 and Abell 2744
Myung Gyoon Lee, Jisu Kang, Jeong Hwan Lee +1
We present the detection of a large population of ultra diffuse galaxies (UDGs) in two massive galaxy clusters, Abell S1063 at and Abell 2744 at , based on F814W…
Can very massive Population III stars produce a super-collapsar?
Sung-Chul Yoon, Jisu Kang, Alexandra Kozyreva
A fraction of the first generation of stars in the early Universe may be very massive () as they form in metal-free environments. Formation of black h…
