JWST Reveals a Candidate Supermassive Black Hole Binary at z=4.3 in the Brightest Sub-millimeter Galaxy in COSMOS-Web

Jed McKinney, Ansh Gupta, Julian B. Munoz +13

We present JWST/NIRSpec PRISM and G395M grating spectroscopy for AzTEC-1, a massive sub-mm bright galaxy at in the COSMOS extragalactic field. The PRISM spectrum reveals s…

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…

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…

Environmental Effects on the Stellar Mass Function in a z~3.3 Overdensity of Galaxies in the COSMOS Field

Ben Forrest, Brian C. Lemaux, Ekta A. Shah +17

We present an analysis of the number density of galaxies as a function of stellar mass (i.e., the stellar mass function, SMF) in the COSMOS field at z~3.3, making a comparison betw…

MAGAZ3NE: Massive, Extremely Dusty Galaxies at Lead to Photometric Overestimation of Number Densities of the Most Massive Galaxies at

Ben Forrest, M. C. Cooper, Adam Muzzin +17

We present rest-frame optical spectra from Keck/MOSFIRE and Keck/NIRES of 16 candidate ultramassive galaxies targeted as part of the Massive Ancient Galaxies at Near-Infrared…
