New Ionization Models and the Shocking Nitrogen Excess at z > 5
Sophia R. Flury, Karla Z. Arellano-Córdova, Edward C. Moran +1
The new era of galaxy evolution studies hearkened in by JWST has led to the discovery of z > 5 galaxies exhibiting excess nitrogen with log(N/O)~1 dex or more than expected from lo…
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…
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…
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 ($M_{\rm…
The Low-Redshift Lyman Continuum Survey: The Roles of Stellar Feedback and ISM Geometry in LyC Escape
Sophia R. Flury, Anne E. Jaskot, Alberto Saldana-Lopez +30
One of the fundamental questions of cosmology is the origin and mechanism(s) responsible for the reionization of the Universe beyond . To address this question, many studie…
The Effect of Radiation and Supernovae Feedback on LyC Escape in Local Star-forming Galaxies
Cody A. Carr, Renyue Cen, Claudia Scarlata +25
Feedback is widely recognized as an essential condition for Lyman continuum (LyC) escape in star-forming galaxies. However, the mechanisms by which galactic outflows clear neutral…
Multivariate Predictors of LyC Escape II: Predicting LyC Escape Fractions for High-Redshift Galaxies
Anne E. Jaskot, Anneliese C. Silveyra, Anna Plantinga +19
JWST is uncovering the properties of ever increasing numbers of galaxies at z>6, during the epoch of reionization. Connecting these observed populations to the process of reionizat…
Multivariate Predictors of LyC Escape I: A Survival Analysis of the Low-redshift Lyman Continuum Survey
Anne E. Jaskot, Anneliese C. Silveyra, Anna Plantinga +19
To understand how galaxies reionized the universe, we must determine how the escape fraction of Lyman Continuum (LyC) photons (fesc) depends on galaxy properties. Using the z~0.3 L…
The JWST-PRIMAL Legacy Survey. A JWST/NIRSpec reference sample for the physical properties and Lyman- absorption and emission of galaxies at
K. E. Heintz, G. B. Brammer, D. Watson +45
One of the surprising early findings with JWST has been the discovery of a strong "roll-over" or a softening of the absorption edge of Ly in a large number of galaxies at ($z\gt…
[Ne v] emission from a faint epoch of reionization-era galaxy: evidence for a narrow-line intermediate mass black hole
J. Chisholm, D. A. Berg, R. Endsley +16
Here we present high spectral resolution NIRSpec observations of GN42437, a low-mass (log(M), compact (pc), extreme starburst galaxy…
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…
