HST's Deep Blue: extremely deep UV imaging to reveal the contributors to reionization
Ilias Goovaerts, Alexander Beckett, Matthew Hayes +12
Understanding galaxy evolution in the epoch of reionization and the effect these galaxies had on the transformation of the intergalactic medium from neutral to ionized, is a key go…
MXDFz4.4: A LyC emitter 250Myr after the epoch of reionization and a first test of Ly-alpha morphology as a tracer of LyC escape at high redshift
Ilias Goovaerts, Marc Rafelski, Alexander Beckett +14
Assessing the contribution of ionizing sources to cosmic reionization is a central goal of extragalactic astrophysics. Understanding and quantifying ionizing escape remains challen…
The Parallel Ionizing Emissivity Survey (PIE). I. Survey design and selection of candidate Lyman Continuum leakers at 3.1<z<3.5
Alexander Beckett, Marc Rafelski, Claudia Scarlata +18
We present the survey design and initial results from the Parallel Ionizing Emissivity (PIE) survey. PIE is a large HST survey designed to detect Lyman continuum (LyC) emitting gal…
Spatially Resolving the Fundamental Elements of Reionization in Galaxies
Xinfeng Xu, Stephan McCandliss, Allison Strom +10
Cosmic reionization marks a critical epoch when the first galaxies ionized the intergalactic medium through the escape of Lyman continuum (LyC) radiation. Young, massive star clust…
Identifying the contributors to cosmic reionization with the Habitable World Observatory: LyC escape calibration in faint galaxies
Annalisa Citro, Cody. A. Carr, Yumi Choi +9
Investigating how small-scale physical processes shape large-scale astrophysical phenomena is one of the key science themes of the Astro2020 decadal Survey. An example of this inte…
Challenging the LyC-Ly relation: strong Ly emitters without LyC leakage at z 2.3
Annalisa Citro, Claudia M. Scarlata, Kameswara B. Mantha +9
The escape fraction of LyC ionizing radiation () is crucial for understanding reionization, yet difficult to measure at . Recently, studies have focused on ca…
