For the past 400 years, astronomers have sought to observe and interpret the Universe by
building more powerful telescopes. These incredible instruments extend the capabilities 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 …

The Leiden Atomic and Molecular Database (LAMDA) collects spectroscopic information
and collisional rate coefficients for molecules, atoms, and ions of astrophysical and …

Abstract The Mid-Infrared Instrument (MIRI) extends the reach of the James Webb Space
Telescope (JWST) to 28.5 μm. It provides subarcsecond-resolution imaging, high sensitivity …

Context. The Medium-Resolution Spectrometer (MRS) provides one of the four operating
modes of the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …

Abstract The James Webb Space Telescope (JWST) is a large, infrared space telescope that
has recently started its science program which will enable breakthroughs in astrophysics …

Carbon is an essential element for life but how much can be delivered to young planets is
still an open question. The chemical characterization of planet-forming disks is a crucial step …

Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au)
regions of protoplanetary disks. Water plays a key role in their formation,–, although it is yet …

We present the data release and data reduction process for the Epoch 1 NIRCam
observations for the Cosmic Evolution Early Release Science Survey (CEERS). These data …
