A Single Line-Emitter Identified in an Unbiased Search with JWST/NIRSpec: Multi-Object Coronagraphy for Slitless Spectroscopy

Mason S. Huberty, Claudia Scarlata, Matthew J. Hayes +13

We report the detection of a previously unknown object with a single emission line within the Hubble Ultra Deep Field, using a new JWST NIRSpec technique called Multi-Object Corona…

Star Cluster Populations in 38 Spiral Galaxies: Evidence for Near-Universal Mass and Age Distributions from PHANGS

Rupali Chandar, Matthew R. Floyd, David A. Thilker +23

We present the largest study to date of star cluster mass and age distributions in nearby galaxies. The analysis is based on a uniformly selected catalog of over 15,000 (36,000) hu…

Mapping the z>=5 SiIV Column Density Distribution onto the Galaxy Stellar Mass Function Using the Cumulative Absorption Cross Section

Kristian Finlator, Sam Patterson, Nora Nava +4

Efforts to constrain directly the activity in low-mass galaxies confront sensitivity limits even in the JWST era. Metal absorbers offer a complementary probe and are easier to dete…

The Stellar Population of NGC 346 in the Small Magellanic Cloud with JWST

J. Jaspers, P. Kavanagh, G. De Marchi +13

NGC 346 is a massive star-forming region located at a distance of 62 kpc, in the Small Magellanic Cloud (SMC). Due to its low metallicity (Z 1/5 Z), it is an…

A Detailed Analysis of Intermediate-scale Structure in Optical Extinction Curves: Expanded Census and Two-family Classification

C. M. Gunasekera, M. Decleir, K. D. Gordon +4

The features of interstellar extinction curves serve as powerful diagnostics for interstellar dust, revealing information about its composition, size distribution, and the physical…

JWST PRIMER: Post-starburst galaxies dominate the low-mass quiescent galaxy population since z~2

Thomas de Lisle, David T. Maltby, Omar Almaini +10

We present the evolution of the stellar mass functions for photometrically selected star-forming, passive and post-starburst galaxies, based on JWST PRIMER observations of the Ultr…
