NGDEEP: A New Non-Parametric Measure of Local Star-Formation and Attenuation at Cosmic Noon
Grace M. Forrey, Raymond C. Simons, Jonathan R. Trump +6
We introduce a new non-parametric technique to quantify the spatially-resolved relationship between the local star-formation rate (SFR) and dust attenuation. We then apply it to 14…

Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…

Extended Enriched Gas in a Multi-Galaxy Merger at Redshift 6.7
Weida Hu, Casey Papovich, Lu Shen +5
Recent JWST observations have uncovered high-redshift galaxies characterized by multiple star-forming clumps, many of which appear to be undergoing mergers. Such mergers, especiall…
