Strong rest-UV emission lines in a "little red dot" AGN at : Early SMBH growth alongside compact massive star formation?
Hollis B. Akins, Caitlin M. Casey, Danielle A. Berg +11
JWST has now revealed a population of broad-line AGN at characterized by a distinctive SED shape, with very red rest-frame optical and very blue rest-frame UV continuum. Whil…
CLASSY XI: Tracing Neutral Gas Properties using UV Absorption Lines and 21-cm Observations
Kaelee S. Parker, Danielle A. Berg, Simon Gazagnes +15
Rest-frame far-ultraviolet (FUV) observations from JWST are revolutionizing our understanding of the high-z galaxies that drove reionization and the mechanisms by which they accomp…
The Effect of Radiation and Supernovae Feedback on LyC Escape in Local Star-forming Galaxies
Cody A. Carr, Renyue Cen, Claudia Scarlata +25
Feedback is widely recognized as an essential condition for Lyman continuum (LyC) escape in star-forming galaxies. However, the mechanisms by which galactic outflows clear neutral…
Shining a Light on the Connections between Galactic Outflows Seen in Absorption and Emission Lines
Xinfeng Xu, Alaina Henry, Timothy Heckman +14
Galactic outflows provide important feedback effects to regulate the evolution of host galaxies. Two primary diagnostics of outflows are broad and/or blueshifted emission and absor…
The case for super-Eddington accretion in JWST broad-line AGN during the first billion years
Erini Lambrides, Rebecca Larson, Kristen Garofali +23
A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…
First direct carbon abundance measured at in the lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Michael W. Topping, Dan Coe +7
Investigating the metal enrichment in the early universe helps us constrain theories about the first stars and study the ages of galaxies. The lensed galaxy MACS0647JD at $z=10.…
Observations of Extremely Metal-Poor O Stars: Weak Winds and Constraints for Evolution Models
O. Grace Telford, John Chisholm, Andreas A. C. Sander +3
Metal-poor massive stars drive the evolution of low-mass galaxies, both locally and at high redshift. However, quantifying the feedback they impart to their local surroundings rema…
CLASSY X: Highlighting Differences Between Partial Covering and Semi-Analytic Modeling in the Estimate of Galactic Outflow Properties
M. Huberty, C. Carr, C. Scarlata +17
Feedback driven massive outflows play a crucial role in galaxy evolution by regulating star formation and influencing the dynamics of surrounding media. Extracting outflow properti…
CHAOS VIII: Far-Ultraviolet Spectra of M101 and The Impact of Wolf-Rayet Stars
Danielle A. Berg, Evan D. Skillman, John Chisholm +8
We investigate the stellar and nebular properties of 9 H II regions in the spiral galaxy M101 with far-ultraviolet (FUV; ~900-2000 Å) and optical (~3200-10000 Å) spectra. We detect…
CLASSY IX: The Chemical Evolution of the Ne, S, Cl, and Ar Elements
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +20
To study the chemical evolution across cosmic epochs, we investigate Ne, S, Cl, and Ar abundance patterns in the COS Legacy Archive Spectroscopic SurveY (CLASSY). CLASSY comprises…
CLusters in the Uv as EngineS (CLUES). II. Sub-kpc scale outflows driven by stellar feedback
Mattia Sirressi, Angela Adamo, Matthew Hayes +17
We analyze the far-ultraviolet spectroscopy of 20 young and massive star clusters (YSCs) in 11 nearby star-forming galaxies. We probe the interstellar gas intervening along the lin…
