Investigating the Electron-capture Supernova Candidate AT 2019abn with JWST Spectroscopy

The Astrophysical Journal Letters
The James Webb Space Telescope (JWST) has opened up a new window to study highly reddened explosive transients. We present results from late-time JWST follow-up spectroscopic observations with NIRSpec and MIRI-LRS of the intermediate-luminosity red ...

A JWST NIRCam/MIRI View of the W51A High-mass Star-forming Region

The Astronomical Journal
We present observations of the W51A region, including the massive protoclusters W51-E and W51-IRS2, with JWST in 10 NIRCam and 5 MIRI filters. In this work, we highlight the most novel features apparent in these images and compare them with other ...

Analysis of Multi-epoch JWST Images of ∼300 Little Red Dots: Tentative Detection of Variability in a Minority of Sources

The Astrophysical Journal
The James Webb Space Telescope (JWST) has revealed a population of red and compact sources at z  ≳ 5 known as “little red dots” (LRDs) that are likely active galactic nuclei (AGNs).

A Multiwavelength Study of Comet C/2022 E3 (ZTF): Complementary ALMA and JWST Investigations of Water and Methanol in Cometary Comae

The Astronomical Journal
Long-period comets, which are often considered to be representative of material in the protoplanetary disk that formed the solar system, are ideal to investigate the question of chemical inheritance in astronomy. Determining the chemistry of comets, both

JWST Observations of Young protoStars (JOYS)

Context. The Mid-InfraRed Instrument (MIRI) on board the James Webb Space Telescope (JWST) allows one to probe the molecular gas composition at mid-infrared (mid-IR) wavelengths with unprecedented resolution and sensitivity.
