JWST Imaging of Edge-on Protoplanetary Disks. V. Flux Ratio Reversal and Disk-edge Structure in the Flying Saucer

The Astrophysical Journal
We present near- and mid-infrared broadband imaging observations of the edge-on protoplanetary disk 2MASS J16281370-2431391, a.k.a. the “Flying Saucer,” obtained with NIRCam and MIRI on board JWST.

Information content of JWST transmission spectroscopy of the exoplanet HAT-P-12b from the optical to the mid-infrared

Astronomy & Astrophysics
Context. The James Webb Space Telescope (JWST) provides low- to medium-resolution spectra with unprecedented precision and broad near- to mid-infrared wavelength coverage, thus enabling the detailed characterization of exoplanet atmospheres.

Progress by the JWST Science Working Group

, 2007
The JWST Science Working Group recently published a comprehensive, top-level review of JWST science in the journal Space Science Reviews (Gardner et al. 2006, SSR, 123, 485). That review paper gives details of the 4 JWST science themes, and describes the

The Perfect Host: JWST Cepheid Observations in a Background-free Type Ia Supernova Host Confirm No Bias in Hubble-constant Measurements

The Astrophysical Journal Letters
Cycle 1 JWST observations of Cepheids in Type Ia supernova (SN Ia) hosts resolved their red-giant-dominated near-infrared backgrounds, sharply reducing crowding and showing that photometric bias in lower-resolution Hubble Space Telescope (HST) data does ...

BEACON: JWST NIRCam Pure-parallel Imaging Survey. III. Constraints on the Ultraviolet Luminosity Function and the Clustering of z ∼ 7–14 Galaxies

The Astrophysical Journal
The James Webb Space Telescope (JWST) has extended the frontier of galaxy detection to redshifts z  > 11, finding a high abundance of UV-bright sources that challenge theoretical models.

Identification of High-redshift Galaxy Overdensities in GOODS-N and GOODS-S

The Astrophysical Journal
We conduct a systematic search for high-redshift galaxy overdensities at 4.9 < z _spec < 8.9 in both the Great Observatories Origins Deep Survey (GOODS)-N and GOODS-S fields using James Webb Space Telescope/Near-Infrared Camera (JWST/NIRCam) imaging from

AGN studies with JWST/MIRI

, 2015
The forthcoming James Webb Space Telescope (JWST) will revolutionize galaxy evolution studies from the epoch of reionisation to the present day. In particular, a new era will be open for mid-IR astronomy, as the JWST Mid-Infrared Instrument (MIRI) will ...

The JWST Resolved Stellar Populations Early Release Science Program. IX. The RR Lyrae Population in WLM with HST and JWST

The Astrophysical Journal
RR Lyrae stars are a common, dependable Population II distance indicator and provide an independent tracer of early star formation. Here, we utilize archival Hubble Space Telescope (HST) Advanced Camera for Surveys and JWST/NIRCam observations of the ...
