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 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…
Constraining Reionization with Lyα Damping-Wing Absorption in Galaxy Spectra: A Machine Learning Model Based on Reionization Simulations
Hyunbae Park, Intae Jung, Hidenobu Yajima +8
Recently, NIRSpec PRISM/CLEAR observations by JWST have begun providing rest-frame UV continuum measurements of galaxies at , revealing signatures of Ly damping-wing…
NGDEEP: The Star Formation and Ionization Properties of Galaxies at
Lu Shen, Casey Papovich, Jasleen Matharu +23
We use JWST/NIRISS slitless spectroscopy from the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey to investigate the physical condition of star-forming galaxi…
Little impact of mergers and galaxy morphology on the production and escape of ionizing photons in the early Universe
S. Mascia, L. Pentericci, M. Llerena +28
Compact, star-forming galaxies with high star formation rate surface densities () are often efficient Lyman continuum (LyC) emitters at , likely as inte…
