MEOW: The increase in the obscured AGN fraction in mid-infrared from 0 < z < 6 with JWST MIRI

Teodora-Elena Bulichi, Gene C. K. Leung, Anna-Christina Eilers +16

Obscured active galactic nuclei (AGN) are often invoked to explain the rapid emergence of young quasars at high redshift and are crucial for building a complete census of AGN activ…

Direct pathway to the Early Supermassive Black Holes: A Red Super-Eddington Quasar in a Massive Starburst Host at

Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +24

We present a panchromatic optical-mm characterization of GNz7q, a recently identified X-ray weak, rapidly growing red quasar embedded within a dusty starburst galaxy at ,…

Clues to inside-out quenching in quiescent galaxies at : Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE

Chloe M. Cheng, Martje Slob, Mariska Kriek +16

[Abridged] Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into quenching and assembly mechanisms. Previous photometri…

Carbon and Iron Deficiencies in Quiescent Galaxies at z=1-3 from JWST-SUSPENSE: Implications for the Formation Histories of Massive Galaxies

Aliza G. Beverage, Martje Slob, Mariska Kriek +20

We present the stellar metallicities and multi-element abundances (C, Mg, Si, Ca, Ti, Cr, and Fe) of 15 massive (log ) quiescent galaxies at z=1-3, derived fro…

Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo

Pablo G. Pérez-González, Francesco D`Eugenio, Bruno Rodríguez del Pino +18

Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells whose mass is dominated by dark matter. Eventually, star formation quenches as gas is de…
