CLASSY XIV: The Nitrogen Exception -- Multi-Phase Enrichment and Feedback in High- Analogs
Bethan L. James, Valentina Abril-Melgarejo, Karla Z. Arellano-Córdova +13
We present a first-of-its-kind analysis of the metal content across two interstellar medium (ISM) phases in a sample of 31 local star-forming galaxies from the COS Legacy Archive S…
The Deepest GLIMPSE of a Dense Gas Cocoon Enshrouding a Little Red Dot
Vasily Kokorev, John Chisholm, Rohan P. Naidu +19
The detection of strong Balmer breaks and absorption features in Little Red Dots (LRDs) suggests they host AGN embedded within dense gas envelopes, potentially powered by super-Edd…
JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization
Hakim Atek, John Chisholm, Vasily Kokorev +44
We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…
Declining metallicity and extended HeII in the outflow of an epoch of reionization analogue galaxy
M. J. Hamel-Bravo, D. B. Fisher, D. A. Berg +5
We present VLT/X-shooter spectroscopy of the extremely metal-poor starburst galaxy SBS 0335-052E, a nearby (D 54 Mpc) analog of high-redshift systems, probing its outflow up…
The first GLIMPSE of the faint galaxy population at Cosmic Dawn with JWST: The evolution of the ultraviolet luminosity function across z~9-15
Iryna Chemerynska, Hakim Atek, Lukas J. Furtak +27
Using ultra-deep JWST NIRCam imaging from the GLIMPSE Survey, enhanced by gravitational lensing of the AbellS1063 cluster, we investigate the faintest galaxies ever observed in the…
Discovery of Multiply Ionized Iron Emission Powered by an Active Galactic Nucleus in a z~7 Little Red Dot
Erini Lambrides, Rebecca Larson, Taylor Hutchison +50
Some of the most puzzling discoveries of NASA's JWST in the early Universe surround the surprising abundance of compact red sources, which show peculiar continuum shapes and broad…
Electron temperature relations in low metallicity, diffuse, and extraplanar gas of starburst galaxies
Magdalena J. Hamel-Bravo, Deanne B. Fisher, Danielle A. Berg +6
In this work, we test the validity of - relations in resolved (10-200~pc) measurements of four nearby, low-metallicity (7.25 12+log(O/H) 8.33), low-mass (…
Leonessa: An Extremely Metal-poor Galaxy Undergoing Secular Chemical Evolution
Joseph A. Breneman, Kristen B. W. McQuinn, Alexander Menchaca +5
Extremely metal-poor (XMP) galaxies are systems with gas-phase oxygen abundances below 5% Solar metallicity (12+log(O/H)7.35). These galaxies populate the metal-poor end…
Emission Line Diagnostics for IMBHs in Dwarf Galaxies: Accounting for BH Seeding and ULX Excitation
Chris T. Richardson, Jordan Wels, Kristen Garofali +13
Dwarf AGN serve as the ideal systems for identifying intermediate mass black holes (IMBHs) down to the most elusive regimes (). However, the ubiquitousl…
A Spectroscopic Survey of Metal-Poor OB Stars in Local Dwarf Galaxy NGC 3109
Abby Mintz, O. Grace Telford, Evan N. Kirby +3
As JWST uncovers increasingly strong evidence that metal-poor, massive stars in early galaxies dominated reionization, observational constraints on the properties of such stars are…
Tentative detection of neutral gas in a Little Red Dot at
Hollis B. Akins, Caitlin M. Casey, John Chisholm +7
JWST has revealed a population of broad-line active galactic nuclei at with remarkably red colors, so-called "Little Red Dots." Ubiquitous Balmer breaks suggest that they har…
GLIMPSE: An ultra-faint 10 Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at
Seiji Fujimoto, Rohan P. Naidu, John Chisholm +32
Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a nov…
