Supernovae Driven Winds Impede Lyman Continuum Escape from Dwarf Galaxies in First 10 Myr

Cody Carr, Renyue Cen, Stephan McCandliss +25

Observations suggest that UV-bright, compact star-forming galaxies produce enough ionizing (Lyman continuum; LyC) photons to reionize the Universe. Yet, the efficiency of LyC escap…

The Ly and Continuum Origins Survey. III. Investigating the Link between Galaxy Morphology, Merger Properties and LyC Escape

Alexandra Le Reste, Anne E. Jaskot, Jordanne Brazie +20

Characterizing the mechanisms and galaxy properties conducive to the emission and escape of ionizing (LyC) emission is necessary to accurately model the Epoch of Reionization, and…

The Lyman-alpha and Continuum Origins Survey II: the connection between the escape of ionizing radiation and Lyman-alpha halos in star-forming galaxies

A. Saldana-Lopez, M. J. Hayes, A. Le Reste +24

One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies. Here, we investigate the connec…

The Lyman-alpha and Continuum Origins Survey. I. Survey description and Ly imaging

Alexandra Le Reste, Claudia Scarlata, Matthew Hayes +25

Understanding the mechanisms driving the escape of ionizing or Lyman continuum (LyC) emission from the interstellar medium of galaxies is necessary to constrain the evolution of re…

A Glimpse of the New Redshift Frontier Through Abell S1063

Vasily Kokorev, Hakim Atek, John Chisholm +31

We report the discovery of two galaxy candidates at redshifts between in JWST observations from the GLIMPSE survey. These robust sources were identified using a combi…

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…

A negligible contribution of two luminous ~ 7.5 galaxies to the ionizing photon budget of reionization

S. Gazagnes, J. Chisholm, R. Endsley +12

We present indirect constraints on the absolute escape fraction of ionizing photons () of the system GN 42912 which comprises two luminous galaxies ($M_{\rm…

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…

A public grid of radiative transfer simulations for Lyman-alpha and metal lines in idealised galactic outflows

Thibault Garel, Léo Michel-Dansac, Anne Verhamme +5

The vast majority of star-forming galaxies are surrounded by large reservoirs of gas ejected from the interstellar medium. Ultraviolet absorption and emission lines represent power…

Comparing the VANDELS sample to a zoom-in Radiative Hydrodynamical Simulation: using the Si II and C II line spectra as tracers of galaxy evolution and Lyman Continuum leakage

Simon Gazagnes, Fergus Cullen, Valentin Mauerhofer +8

We compare mock ultraviolet C II and Si II absorption and emission line features generated using a ~10 virtual galaxy with observations of 131 galaxies from the…

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…

Using Mg II Doublet to Predict the Lyman Continuum Escape Fraction from 14 HETDEX Galaxies

Victoria Salazar, Floriane Leclercq, John Chisholm +2

Indirect diagnostics of Lyman continuum (LyC) escape are needed to constrain which sources reionized the universe. We used Mg II to predict the LyC escape fraction (fesc(LyC)) in 1…
