Spatially Resolved Properties of High Redshift Galaxies in the SMACS0723 JWST ERO Field
Clara Giménez-Arteaga, Pascal A. Oesch, Gabriel B. Brammer +10
We present the first spatially resolved measurements of galaxy properties in the JWST ERO SMACS0723 field. We perform a comprehensive analysis of five galaxies with spectro…
21cmfish: Fisher-matrix framework for fast parameter forecasts from the cosmic 21-cm signal
Charlotte A. Mason, Julian B. Muñoz, Bradley Greig +2
The 21-cm signal from neutral hydrogen in the early universe will provide unprecedented information about the first stars and galaxies. Extracting this information, however, requir…
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…
Dilution of chemical enrichment in galaxies 600 Myr after the Big Bang
Kasper E. Heintz, Gabriel B. Brammer, Clara Giménez-Arteaga +10
Galaxies throughout the last 12 Gyr of cosmic time follow a single, universal relation that connects their star-formation rates (SFRs), stellar masses () and chemical abun…
The production of ionizing photons in UV-faint z~3-7 galaxies
Gonzalo Prieto-Lyon, Victoria Strait, Charlotte A. Mason +20
The demographics of the production and escape of ionizing photons from UV-faint early galaxies is a key unknown in discovering the primary drivers of reionization. With the advent…
Early results from GLASS-JWST. XIV: A spectroscopically confirmed protocluster 650 million years after the Big Bang
Takahiro Morishita, Guido Roberts-Borsani, Tommaso Treu +39
We present the spectroscopic confirmation of a protocluster at behind the galaxy cluster Abell2744 (hereafter A2744-z7p9OD). Using JWST NIRSpec, we find seven galaxies wit…
