Massive Galaxies Form Early and Gray: Stellar Assembly and Dust Attenuation at from CAPERS
Katherine Chworowsky, Steven L. Finkelstein, Anthony J. Taylor +27
The stellar mass assembly of massive galaxies in the first few billion years of cosmic history remains a central challenge in galaxy formation. Galaxies with $M_\star \gtrsim 10^{1…
Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
Net-zero gas inflow: Measurement of the gas consumption history of a massive quiescent galaxy
Jan Scholtz, Francesco D'Eugenio, Roberto Maiolino +23
JWST is discovering increasing numbers of quiescent galaxies 1--2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation an…
Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo
Pablo G. Pérez-González, Francesco D`Eugenio, Bruno RodrÃguez 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…
GA-NIFS: High number of dual active galactic nuclei at z~3
Michele Perna, Santiago Arribas, Isabella Lamperti +23
Merger events can trigger gas accretion onto supermassive black holes (SMBHs) located at the centre of galaxies, and form close pairs of AGN. The fraction of AGN in pairs offers cr…
The Rise of Faint, Red AGN at : A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro +54
We present a sample of 341 "little red dots" (LRDs) spanning the redshift range using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. Unlike past use of…
