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 $z = 4.34$ in the COSMOS extragalactic field. The PRISM spectrum reveals s…

MAGAZ3NE: Spatially Resolved Ages and Chemical Abundances of Ultra-Massive Quiescent Galaxies at z $\sim$ 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 [ $α$ /Fe] in three ultra-massive ( $log (M_{*} / M_{⊙}) > 11$ ), compact ( $R_{e} ≲ 2$ kpc) quie…
