ODIN: Rest-frame Optical Morphologies and Star Formation Activity of Lyα Emitters at z=2.4, 3.1, and 4.5
Sang Hyeok Im, Ho Seong Hwang, Jeong Hwan Lee +19
We analyze the rest-frame optical (~8000 Å) morphologies and star formation activity of Lyα emitters (LAEs) at redshifts , , and , identified in the ODIN survey. To…
Search for Slow Bars in Two Barred Galaxies with Nuclear Structures: NGC 6951 and NGC 7716
Yun Hee Lee, Ho Seong Hwang, Virginia Cuomo +9
We investigate two barred galaxies with nuclear structures, NGC 6951 and NGC 7716, to examine whether they host slow bars. Using Gemini/GMOS long-slit spectroscopy, we calculate th…
Uncovering the Ghostly Remains of an Extremely Diffuse Satellite in the Remote Halo of NGC 253
Sakurako Okamoto, Annette M. N. Ferguson, Nobuo Arimoto +12
We present the discovery of NGC253-SNFC-dw1, a new satellite galaxy in the remote stellar halo of the Sculptor Group spiral, NGC 253. The system was revealed using deep resolved st…
Morphology of Galaxies in JWST Fields: Initial Distribution and Evolution of Galaxy Morphology
Jeong Hwan Lee, Changbom Park, Ho Seong Hwang +1
A recent study from the Horizon Run (HR5) cosmological simulation has predicted that galaxies with in the cosmic morning ($10\gtrsim z\gtr…
