Rapid Quenching of Galaxies at Cosmic Noon

Minjung Park, Sirio Belli, Charlie Conroy +6

The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and wha…

Widespread rapid quenching at cosmic noon revealed by JWST deep spectroscopy

Minjung Park, Sirio Belli, Charlie Conroy +16

Massive quiescent galaxies in the young universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical me…

UNCOVER: A NIRSpec Census of Lensed Galaxies at z=8.50-13.08 Probing a High AGN Fraction and Ionized Bubbles in the Shadow

Seiji Fujimoto, Bingjie Wang, John Weaver +33

We present JWST NIRSpec prism spectroscopy of gravitationally lensed galaxies at found behind the massive galaxy cluster Abell 2744 in the UNCOVER Cycle 1 Treasury Prog…

JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon

Chloë E. Benton, Erica J. Nelson, Tim B. Miller +10

Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon -- the peak of cosmic star formation history -- appear disk-dominated, leaving the origin of the…

JADES + JEMS: A Detailed Look at the Buildup of Central Stellar Cores and Suppression of Star Formation in Galaxies at Redshifts 3 < z < 4.5

Zhiyuan Ji, Christina C. Williams, Sandro Tacchella +30

We present a spatially resolved study of stellar populations in 6 galaxies with stellar masses at using 14-filter JWST/NIRCam imaging from the JA…
