We describe new JWST/NIRSpec observations of galaxies at z≳ 7 taken from the CEERS
survey. Previous observations of this area have revealed associations of Lyα emitters at …

JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-
resolution infrared view of the distant Universe. Adding to the new legacy of JWST …

Abstract High-resolution James Webb Space Telescope (JWST) observations can test
confusion-limited Hubble Space Telescope (HST) observations for a photometric bias that …

Spectroscopy with the James Webb Space Telescope has opened the possibility of
identifying moderate-luminosity active galactic nuclei (AGNs) in the early Universe, at and …

ABSTRACT A substantial number of ultra-high redshift (8≲ z≲ 17) galaxy candidates have
been detected with JWST, posing the question: Are these observational results surprising in …

Abstract The James Webb Space Telescope is revealing a new population of dust-reddened
broad-line active galactic nuclei (AGN) at redshifts z≳ 5. Here we present deep …

We use deep imaging from the JWST Advanced Deep Extragalactic Survey (JADES) to
study the evolution of the ionizing photon production efficiency, ξion. We estimate ξion for a …

Jupiter's moon Europa has a subsurface ocean beneath an icy crust. Conditions within the
ocean are unknown, and it is unclear whether it is connected to the surface. We observed …

ABSTRACT We use CANUCS JWST/NIRCam imaging of galaxies behind the gravitationally-
lensing cluster MACS J0417. 5-1154 to investigate star formation burstiness in low-mass …

Early JWST observations have uncovered a population of red sources that might represent a
previously overlooked phase of supermassive black hole growth,–. One of the most …
