JWST UNCOVERs the Optical Size–Stellar Mass Relation at 4 < z < 8: Rapid Growth in the Sizes of Low-mass Galaxies in the First Billion Years of the Universe
We study the rest-frame optical and ultraviolet (UV) morphology of galaxies in the first billion years of the Universe. Using James …
RUBIES spectroscopically confirms the high number density of quiescent galaxies from mathbf2<z<5
We present the number density of massive ( mathlog (M_*/M_⊙) > 10.3 ) quiescent galaxies at 2<z<5 using JWST NIRSpec PRISM …
JWST+ALMA reveal the build up of stellar mass in the cores of dusty star-forming galaxies at Cosmic Noon
Dusty star-forming galaxies have long been suspected to serve as the missing evolutionary bridge between the star-forming and quiescent …
Measuring Emission Lines with JWST MegaScience Medium Bands: A New Window into Dust and Star Formation at Cosmic Noon
We demonstrate the power of JWST-NIRCam medium-band photometry to measure emission line fluxes and study the dust and star formation …
MINERVA: A NIRCam Medium Band and MIRI Imaging Survey to Unlock the Hidden Gems of the Distant Universe
We present an overview of the MINERVA survey, a 259.8 hour (prime) and 127 hour (parallel) Cycle 4 treasury program on the James Webb …
DUALZ—Deep UNCOVER-ALMA Legacy High-Z Survey
We present the survey design and initial results of the Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 9 program of DUALZ, …
Investigating photometric and spectroscopic variability in the multiply imaged little red dot A2744-QSO1
JWST observations have uncovered a new population of red, compact objects at high redshifts dubbed ``little red dots’’ …
Taking a Break at Cosmic Noon: Continuum-selected Low-mass Galaxies Require Long Burst Cycles
While bursty star formation in low-mass galaxies has been observed in local populations and reproduced in simulations, the dormant …
UNCOVERing the High-redshift AGN Population among Extreme UV Line Emitters
JWST has revealed diverse new populations of high-redshift (z ∼ 4–11) active galactic nuclei (AGNs) and extreme star-forming galaxies …
The Structure and Formation Histories of Low-Mass Quiescent Galaxies in the Abell 2744 Cluster Environment
Low-mass quiescent galaxies are thought to predominantly reside in overdense regions, as environmental effects are often invoked to …
