Reionization driven by the few: the ionizing budget of galaxies at z=5-10 from JWST/NIRSpec

Emma Giovinazzo, Pascal A. Oesch, Anne Verhamme +5

The sources responsible for the Epoch of Reionization (EoR), the last major phase transition of the Universe, remain highly elusive. While JWST has begun to illuminate the properti…

Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application

Xinfeng Xu, Drummond Fielding, Timothy Heckman +12

Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…

Breaking Through the Cosmic Fog: JWST/NIRSpec Constraints on Ionizing Photon Escape in Reionization-Era Galaxies

Emma Giovinazzo, Pascal A. Oesch, Andrea Weibel +15

The escape fraction of Lyman continuum photons (fesc(LyC)) is the last key unknown in our understanding of cosmic reionization. Directly estimating the escape fraction (fesc) of io…

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…

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…

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…

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…

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…

Absorption Troughs of Lyman Alpha Emitters in HETDEX

Laurel H. Weiss, Dustin Davis, Karl Gebhardt +21

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is designed to detect and measure the redshifts of more than one million Ly emitting galaxies (LAEs) between $1.88 < z…

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…

The origin of the escape of Lyman alpha and ionizing photons in Lyman Continuum Emitters

S. Gazagnes, J. Chisholm, D. Schaerer +2

Identifying the mechanisms driving the escape of Lyman Continuum (LyC) photons is crucial to find Lyman Continuum Emitter (LCE) candidates. To understand the physical properties in…
