Through Thick and Thin: The Cosmic Evolution of Disk Scale Height

Si-Yue Yu, Luis C. Ho, Takafumi Tsukui +16

To investigate the formation and evolution of vertical structures in disk galaxies, we measure global scale heights, averaging thin and thick components whe…

An ultra-high-resolution map of (dark) matter

Diana Scognamiglio, Gavin Leroy, David Harvey +38

Ordinary matter-including particles such as protons and neutrons-accounts for only about one sixth of all matter in the Universe. The rest is dark matter, which does not emit or ab…

Physical properties of galaxies and the UV Luminosity Function from to in COSMOS-Web

Maximilien Franco, Caitlin M. Casey, Hollis B. Akins +37

We present measurements of the rest-frame ultraviolet luminosity function (UVLF) in three redshift bins over -14 from the JWST COSMOS-Web survey. Our samples, selected us…

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…

COSMOS-Web: Unraveling the Evolution of Galaxy Size and Related Properties at

Lilan Yang, Jeyhan S. Kartaltepe, Maximilien Franco +26

We measure galaxy sizes from using COSMOS-Web, the largest-area JWST imaging survey to date, covering 0.54 deg. We analyze the rest-frame optical (~5000A) si…
