Spiral Morphology and Radial Migration: Kinematically heating, cooling, and cold
Kathryne J. Daniel, M. E. Wisz, Karen L. Masters +3
Transient spiral arms are known to drive radial redistribution of stars and thus could play a central role in shaping disk galaxies, including modifying, over time, the age, chemic…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5
Marie Wisz, Marc Rafelski, Grecco Oyarzun +10
Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conte…
MAGAZ3NE: Dust Deficiency in Ultramassive Quiescent Galaxies at with ALMA Observations
Wenjun Chang, Gillian Wilson, Ben Forrest +14
A major challenge in identifying massive quiescent galaxies at is distinguishing truly passive systems from dust-obscured star-forming galaxies, as both populations exhibit s…
MAGAZ3NE: Far-IR and Radio Insights into the Nature and Properties of Ultramassive Galaxies at
Wenjun Chang, Gillian Wilson, Ben Forrest +12
Deep and wide-field near-infrared (NIR) surveys have recently discovered and confirmed ultramassive galaxies (UMGs; ) spectroscopically at high redsh…
Excavating The Ruins: an Ancient Galaxy Which Formed in the First 500 Myr
Ian McConachie, Jacqueline Antwi-Danso, Wenjun Chang +14
We present the analysis of an ancient galaxy at which we dub ``Eridu.'' Simultaneously modeling the JWST/NIRSpec G140M and G235M spectra from the SMILES program and $0.4-…
