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…
CLASSY XIII. Cutting through the Clouds - Comparing Indirect Tracers of Ionizing Photon Escape
Kaelee S. Parker, Danielle A. Berg, John Chisholm +25
The Epoch of Reionization (EoR) provides critical insights into the role of early galaxies in shaping the ionization state of the universe. However, because of the opacity of the i…
CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25
We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…
CLUES III: Do User Choices Impact The Results of SED Fitting? Tests of 'Off-The-Shelf' Stellar Population and Dust Extinction Models in the CLUES Sample
Andrew Mizener, Daniela Calzetti, Angela Adamo +10
The simple stellar population models produced by stellar population and spectral synthesis (SPS) codes are used as spectral templates in a variety of astrophysical contexts. In thi…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
JWST/MIRI detection of [Ne V] and [Ne VI] in M83: Evidence for the long sought-after AGN?
Svea Hernandez, Linda J. Smith, Logan H. Jones +16
We report the first detections of [Ne V] 14.3 μm and [Ne VI] 7.7 μm at high confidence (S/N>=6) in the nuclear region of the nearby spiral galaxy M83. Emission line maps of these h…
