We describe new ultradeep James Webb Space Telescope (JWST) NIRSpec PRISM and grating spectra for the galaxies JADES-GS-z11-0 ( ${z}_{\mathrm{spec}}={11.122}_{-0.003}^{+0.005}$ ) and JADES-GS-z13-0 ( ${z}_{\mathrm{spec}}={13.20}_{-0.04}^{+0.03}$ ), t

We present near-infrared (NIR) spectroscopy using the MMT and Magellan infrared spectrograph for a sample of 29 massive galaxies ( $\mathrm{log}\ {M}_{* }/{M}_{\odot }\gtrsim 10$ ) at z ∼ 0.7 with optical spectroscopy from the Large Early Galaxy As

We present a spatially resolved study of stellar populations in six galaxies with stellar masses M _* ∼ 10 ^10 M _☉ at z ∼ 3.7 using 14-filter James Webb Space Telescope (JWST)/NIRCam imaging from the JADES and JEMS surveys. The six galaxies ar

One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultrared flattened objects, or UFOs) among the optically faint galaxy (OFG) population otherwise thought to be compact.

WASP-69 b is a hot, inflated, Saturn-mass planet (0.26 M _Jup ) with a zero-albedo equilibrium temperature of 963 K. Here, we report the JWST 2–12 μ m emission spectrum of the planet consisting of two eclipses observed with NIRCam grism time serie

We characterize the earliest galaxy population in the JADES Origins Field, the deepest imaging field observed with JWST. We make use of ancillary Hubble Space Telescope optical images (five filters spanning 0.4–0.9 μ m) and novel JWST images with

We study 31 little red dots (LRD) detected by JADES/NIRCam and covered by the SMILES/MIRI survey, of which ∼70% are detected in the two bluest MIRI bands and 40% in redder MIRI filters. The median/quartiles redshifts are $z={6.9}_{5.9}^{7.7}$ (55%

Understanding the coevolution of supermassive black holes and their host systems requires a comprehensive census of active galactic nuclei (AGNs) behavior across a wide range of redshift, luminosity, obscuration level, and galaxy properties. We repor

The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this study, we leverage moderate spectral resolution observations ( R ∼ 2700)

We use SEDz* —a code designed to chart the star formation histories (SFHs) of 6 < z < 12 galaxies—to analyze the spectral energy distributions (SEDs) of 894 galaxies with deep JWST/NIRCam imaging by JADES in the GOODS-S field. We show how SEDz* m
