Early Results from GLASS-JWST. XIX: A High Density of Bright Galaxies at in the Abell 2744 Region
Marco Castellano, Adriano Fontana, Tommaso Treu +38
We report the detection of a high density of redshift galaxies behind the foreground cluster Abell 2744, selected from imaging data obtained recently with NIRCam onbo…
COSMOS-Web: An Overview of the JWST Cosmic Origins Survey
Caitlin M. Casey, Jeyhan S. Kartaltepe, Nicole E. Drakos +82
We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations…
A Magnified Compact Galaxy at Redshift 9.51 with Strong Nebular Emission Lines
Hayley Williams, Patrick L. Kelly, Wenlei Chen +21
Ultraviolet light from early galaxies is thought to have ionized gas in the intergalactic medium. However, there are few observational constraints on this epoch because of the fain…
The nature of an ultra-faint galaxy in the cosmic Dark Ages seen with JWST
Guido Roberts-Borsani, Tommaso Treu, Wenlei Chen +44
In the first billion years after the Big Bang, sources of ultraviolet (UV) photons are believed to have ionized intergalactic hydrogen, rendering the Universe transparent to UV rad…
Early results from GLASS-JWST. IV: Spatially resolved metallicity in a low-mass galaxy with NIRISS
Xin Wang, Tucker Jones, Benedetta Vulcani +19
We report the first gas-phase metallicity map of a distant galaxy measured with the James Webb Space Telescope (JWST). We use the NIRISS slitless spectroscopy acquired by the GLASS…
Early results from GLASS-JWST. V: the first rest-frame optical size-luminosity relation of galaxies at
Lilan Yang, T. Morishita, N. Leethochawalit +23
We present the first rest-frame optical size-luminosity relation of galaxies at , using the NIRCam imaging data obtained by the GLASS James Webb Space Telescope Early Release…
