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…
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…
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…
Constraints on the Lyman Continuum Escape from Low-mass Lensed Galaxies at 1.3 z 3.0
Intae Jung, Henry C. Ferguson, Matthew J. Hayes +17
Low-mass galaxies can significantly contribute to reionization due to their potentially high Lyman continuum (LyC) escape fraction and relatively high space density. We present a c…
Ubiquitous broad-line emission and the relation between ionized gas outflows and Lyman continuum escape in Green Pea galaxies
R. O. Amorín, M. Rodríguez-Henríquez, V. Fernández +29
We report observational evidence of highly turbulent ionized gas kinematics in a sample of 20 Lyman continuum (LyC) emitters (LCEs) at low redshift (). Detailed Gaussian…
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…
