MAGAZ3NE: Spatially Resolved Ages and Chemical Abundances of Ultra-Massive Quiescent Galaxies at z 3.5 using JWST/NIRSpec IFU
Adit H. Edward, Jacqueline Antwi-Danso, Adam Muzzin +14
We present spatially-resolved measurements of stellar age, [Fe/H], and [/Fe] in three ultra-massive (), compact ( kpc) quie…
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…
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 $0.4-…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
Distinct origins of environmentally quenched galaxies in the core and outer virialised regions of massive clusters at
Guillaume Hewitt, Florian Sarron, Michael L. Balogh +15
High-redshift () galaxy clusters are the domain where environmental quenching mechanisms are expected to emerge as important factors in the evolution of the quiescent galax…
The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters
Adit H. Edward, Michael L. Balogh, Yannick M. Bahe +21
We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between in the COSMOS field, down to a mass limit of M$_{\odot…
