The metallicities of little red dot host galaxies: LRDs are metal poor, but not pristine
G. P. Nikopoulos, D. Watson, C. L. Pollock +4
Little Red Dots (LRDs) are a population of high-z sources discovered by JWST whose compactness, broad permitted lines, strong absorption features, continuum shapes and luminosities…
JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases
Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23
Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…
Chemical signatures from the first stars embedded in metal-poor gas in galaxies at cosmic dawn
Clara L. Pollock, Kasper E. Heintz, Elka Rusta +15
The first generation of stars formed from pristine, neutral hydrogen gas. The most massive of these exploded as supernovae within a few million years of their birth, producing the…
JADES: A Prominent Galaxy Overdensity Candidate within the First 500 Myr
Zihao Wu, Daniel J. Eisenstein, Benjamin D. Johnson +20
We report a galaxy overdensity candidate at in the JWST Advanced Deep Extragalactic Survey (JADES). This overdensity contains 18 galaxies with consistent photometric…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: Photometrically Selected Galaxy Candidates at z > 8
Kevin N. Hainline, Daniel J. Eisenstein, Lily Whitler +34
We present a sample of 2081 sources selected at photometric redshift across the JADES DR5 data release in GOODS-S and GOODS-N over a total area of 469 squar…
Dust enrichment from core-collapse supernovae and extinction curves in the high-redshift universe
Koki Otaki, Raffaella Schneider, Simone Bianchi +4
Recent JWST observations have revealed that some galaxies at generally exhibit relatively flat ultraviolet (UV) attenuation curves and a weak UV bump. These features…
