We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hr
treasury program conducted by the James Webb Space Telescope in its first cycle of …

We summarize the history, concept, scientific program, and technical performance of the
James Webb Space Telescope (JWST, Webb; Gardner et al. 2006). This paper points to and …

Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a
crucial avenue for unlocking the formation and evolution of exoplanetary systems,. Access to …

The TRAPPIST-1 system is remarkable for its seven planets that are similar in size, mass,
density and stellar heating to the rocky planets Venus, Earth and Mars in the Solar System …

We present JWST NIRSpec spectroscopy for 11 galaxy candidates with photometric
redshifts of z≃ 9− 13 and M UV∈[− 21,− 18] newly identified in NIRCam images in the …

We present pure spectroscopic constraints on the UV luminosity functions and cosmic star
formation rate (SFR) densities from 25 galaxies at z spec= 8.61–13.20. By reducing the …

Abstract The Cosmic Gems arc is among the brightest and highly magnified galaxies
observed at redshift z≈ 10.2 (ref.). However, it is an intrinsically ultraviolet faint galaxy, in the …

Abstract The Near-Infrared Spectrograph (NIRSpec) is one of the four focal plane
instruments on the James Webb Space Telescope. In this paper, we summarize the in-orbit …

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 …

We present emission-line measurements and physical interpretations for a sample of 117 [O
iii] emitting galaxies at z= 5.33–6.93, using the first deep JWST/NIRCam wide-field slitless …
