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…

Resolving dust and Lyα emission in a lensed galaxy at the epoch of reionization with JWST/CANUCS

V. Markov, M. Bradač, V. Estrada-Carpenter +20

Lyman emission is highly sensitive to dust and neutral hydrogen and is therefore expected to be strongly suppressed in dusty or gas-rich galaxies during the epoch of reionizat…

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…

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…

Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr

Roberta Tripodi, Nicholas Martis, Vladan Markov +29

The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
