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…
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…
A core in a star-forming disc as evidence of inside-out growth in the early Universe
William M. Baker, Sandro Tacchella, Benjamin D. Johnson +36
The physical processes that establish the morphological evolution and the structural diversity of galaxies are key unknowns in extragalactic astrophysics. Here we report the findin…
Birth of the Galactic Disk Revealed by the H3 Survey
Charlie Conroy, David H. Weinberg, Rohan P. Naidu +12
We use chemistry ([alpha/Fe] and [Fe/H]), main sequence turnoff ages, and kinematics determined from H3 Survey spectroscopy and Gaia astrometry to identify the birth of the Galacti…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
JWST-JADES. Possible Population III signatures at z=10.6 in the halo of GN-z11
Roberto Maiolino, Hannah Uebler, Michele Perna +32
Finding the first generation of stars formed out of pristine gas in the early Universe, known as Population III (PopIII) stars, is one of the most important goals of modern astroph…
