An Updated Characterization of Luminous Lyα emitters at the End of Reionization
Yuanhang Ning, Zheng Cai, Linhua Jiang +5
We present a multi-wavelength physical characterization of 14 luminous Ly emitters (LAEs) at , integrating deep ground-based Magellan/M2FS spectroscopy with heteroge…
A multi-wavelength investigation of spiral structures in galaxies with JWST
Boris S. Kalita, Si-Yue Yu, John D. Silverman +18
Recent JWST observations have revealed the prevalence of spiral structures at . Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain…
Spiral Structure Boosts Star Formation in Disk Galaxies
Si-Yue Yu, Luis C. Ho, Jing Wang
We investigate the impact of spiral structure on global star formation using a sample of 2226 nearby bright disk galaxies. Examining the relationship between spiral arms, star form…
CSST Preparations: Galaxy Completeness and Sérsic Profile Fitting across the Wide, Deep, and Extreme Fields
Ziqi Ma, Si-Yue Yu, Taotao Fang +3
The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To…
Global Spiral Density Wave Modes in Protoplanetary Disks: Morphology of Spiral Arms
Enze Chen, Si-Yue Yu, Luis C. Ho
We analyze two-armed global spiral density wave modes generated by gravitational instability in razor-thin, non-viscous, self-gravitating protoplanetary disks to understand the dep…
COSMOS-Web: Comprehensive Data Reduction for Wide-Area JWST NIRCam Imaging
Maximilien Franco, Caitlin M. Casey, Anton M. Koekemoer +37
We present the data reduction methodology used for the COSMOS-Web survey JWST NIRCam data. Covering 0.54 deg^2 with four broadband filters (F115W, F150W, F277W, F444W) and a total…
