UNCOVER: Illuminating the Early Universe-JWST/NIRSpec Confirmation of z > 12 Galaxies
Observations of high-redshift galaxies provide a critical direct test to the theories of early galaxy formation, yet to date, only …
Quantifying the Effects of Known Unknowns on Inferred High-redshift Galaxy Properties: Burstiness, the IMF, and Nebular Physics
The era of the James Webb Space Telescope ushers stellar population models into uncharted territories, particularly at the …
UNCOVER: The rest ultraviolet to near infrared multiwavelength structures and dust distributions of sub-millimeter-detected galaxies in Abell 2744
With the wavelength coverage, sensitivity, and high spatial resolution of JWST, it is now possible to peer through the dust attenuation …
DUALZ: Deep UNCOVER-ALMA Legacy High-Z Survey
We present the survey design and initial results of the ALMA Cycle 9 program of DUALZ, which aims to establish a joint ALMA and JWST …
Dust attenuation, dust content, and geometry of star-forming galaxies
We analyse the joint distribution of dust attenuation and projected axis ratios, together with galaxy size and surface brightness …
UNCOVER spectroscopy confirms a surprising ubiquity of AGN in red galaxies at z>5
JWST is revealing a new population of dust-reddened broad-line active galactic nuclei (AGN) at redshifts zrsim5. Here we present deep …
UNCOVER: The Growth of the First Massive Black Holes from JWST/NIRSpec-Spectroscopic Redshift Confirmation of an X-Ray Luminous AGN at z = 10.1
The James Webb Space Telescope is now detecting early black holes (BHs) as they transition from “seeds” to supermassive BHs. Recently, …
A supermassive black hole in the early universe growing in the shadows
Early JWST observations have uncovered a new, substantial population of red sources that might represent a previously overlooked phase …
First spectroscopic observations of the galaxies that reionized the Universe
Low-mass galaxies in the early universe are believed to be the building blocks of present-day galaxies. These fledgling systems likely …
Rapid Quenching of Galaxies at Cosmic Noon
The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent …
