The Role of Galaxy Mergers in the High Redshift Universe with Deep JWST Extragalactic Fields

openWe analyze the redshift evolution of major galaxy merger pair fractions using deep multi-band photometry from the ASTRODEEP-JWST catalogs, covering seven extragalactic fields (CEERS, Abell2744, NGDEEP, PRIMER-COSMOS, PRIMER-UDS, JADES-GN, and JADES ...

Deconvolution of JWST/MIRI Images: Applications to an Active Galactic Nucleus Model and GATOS Observations of NGC 5728

The Astronomical Journal
The superb image quality, stability, and sensitivity of JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present an assessment of several deconvolution approaches to improve image quality and

A Single Power Law for the TRAPPIST-1 Flare Distribution across 4 Orders of Magnitude in Energy

The Astrophysical Journal Letters
TRAPPIST-1 is an ultracool dwarf that flares frequently. These flares shape the surrounding planets’ high-energy irradiation environment, with consequences for atmospheric chemistry and escape, and they can contaminate transmission spectroscopy of those ...

A Census from JWST of Extreme Emission-line Galaxies Spanning the Epoch of Reionization in CEERS [PDF]

We present a sample of 1165 extreme emission-line galaxies (EELGs) at 4 5000 Å. JWST/NIRSpec spectroscopic observations of a subset (34) of the photometrically selected EELGs validate our selection method: All spectroscopically observed EELGs confirm ...
