Physical Origins of Outflowing Cold Clouds in Local Star-forming Dwarf Galaxies
Zixuan Peng, Crystal L. Martin, Zirui Chen +10
We study the physical origins of outflowing cold clouds in a sample of 14 low-redshift dwarf ( ) galaxies from the COS Legacy Archive Spectros…
A Simulated Galaxy Laboratory: Exploring the Observational Effects on UV Spectral Absorption Line Measurements
R. Michael Jennings, Alaina Henry, Valentin Mauerhofer +13
Ultraviolet absorption line spectroscopy is a sensitive diagnostic for the properties of interstellar and circumgalactic gas. Down-the-barrel observations, where the absorption is…
Synergistic Radiative Transfer Modeling of MgII and Lyα Emission in Multiphase, Clumpy Galactic Environments: Application to Low-Redshift Lyman Continuum Leakers
Zhihui Li, Max Gronke, Timothy Heckman +9
We conducted systematic radiative transfer (RT) modeling of the Mg II doublet line profiles for 33 low-redshift Lyman continuum (LyC) leakers, and Ly modeling for a subset of si…
Lyman Continuum leakage from massive leaky starbursts: A different class of emitters?
Namrata Roy, Timothy Heckman, Alaina Henry +11
The origin of Lyman Continuum (LyC) photons responsible for reionizing the universe remains a mystery, with the fraction of escaping LyC photons from galaxies at z 6 to 12 be…
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…
DIISC Survey: Deciphering the Interplay Between the Interstellar Medium, Stars, and the Circumgalactic Medium Survey
Sanchayeeta Borthakur, Mansi Padave, Timothy Heckman +13
We present the Deciphering the Interplay between the Interstellar medium, Stars, and the Circumgalactic medium (DIISC) Survey. This survey is designed to investigate the correlatio…
The Low-Redshift Lyman Continuum Survey: The Roles of Stellar Feedback and ISM Geometry in LyC Escape
Sophia R. Flury, Anne E. Jaskot, Alberto Saldana-Lopez +30
One of the fundamental questions of cosmology is the origin and mechanism(s) responsible for the reionization of the Universe beyond . To address this question, many studie…
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…
DIISC-IV: DIISCovery of Anomalously Low Metallicity H II Regions in NGC 99: Indirect Evidence of Gas Inflows
Alejandro J. Olvera, Sanchayeeta Borthakur, Mansi Padave +6
As a part of the Deciphering the Interplay between the Interstellar medium, Stars, and the Circumgalactic medium (DIISC) survey, we investigate indirect evidence of gas inflow into…
Multivariate Predictors of LyC Escape II: Predicting LyC Escape Fractions for High-Redshift Galaxies
Anne E. Jaskot, Anneliese C. Silveyra, Anna Plantinga +19
JWST is uncovering the properties of ever increasing numbers of galaxies at z>6, during the epoch of reionization. Connecting these observed populations to the process of reionizat…
Multivariate Predictors of LyC Escape I: A Survival Analysis of the Low-redshift Lyman Continuum Survey
Anne E. Jaskot, Anneliese C. Silveyra, Anna Plantinga +19
To understand how galaxies reionized the universe, we must determine how the escape fraction of Lyman Continuum (LyC) photons (fesc) depends on galaxy properties. Using the z~0.3 L…
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…
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…
Linking Mg II and [O II] spatial distribution to ionizing photon escape in confirmed LyC leakers and non-leakers
Floriane Leclercq, John Chisholm, Wichahpi King +29
The geometry of the neutral gas in and around galaxies is a key regulator of the escape of ionizing photons. We present the first statistical study aiming at linking the neutral an…
