EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53
Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19
We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…
The Evolution of the SFR-M_* relation at 0.1<z<4: Environmental and Morphological Dependencies
Kaimin He, Ke Shi, Jun Toshikawa +2
We present a comprehensive study of the relationship between star formation rate (SFR) and stellar mass (M_*) from z = 0.1 to z = 4 using a mass-complete sample of approximately 29…
Narrowband Imaging of a z=3.24 Protocluster: Insights from [O III] Emitting Galaxies
Ke Shi, Jun Toshikawa, XianZhong Zheng +2
We present a narrowband imaging on a spectroscopically confirmed protocluster ``D4UD01'' at z=3.24 using CFHT/WIRCam. We identify a sample of 24 [O III] emission line galaxies in t…
Mining for Protoclusters at from Photometric Datasets with Deep Learning
Yoshihiro Takeda, Nobunari Kashikawa, Kei Ito +9
Protoclusters are high- overdense regions that will evolve into clusters of galaxies by , making them ideal for studying galaxy evolution expected to be accelerated by envi…
