HST's Deep Blue: extremely deep UV imaging to reveal the contributors to reionization

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…
Simulating Chemical Abundances in the Circumstellar Nebula of the Late Stage Binary RY Scuti
Sarah H. Taft, Robert D. Gehrz, Charles E. Woodward +3
RY Scuti, thought to be a Wolf-Rayet (WR) progenitor, is a massive, post-main-sequence, binary star system undergoing Roche lobe overflow (RLOF). SOFIA (+FORCAST) spectroscopy of t…

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…
On the Average Ultraviolet Emission Line Spectra of High-Redshift Galaxies: Hot and Cold, Carbon-poor, Nitrogen-modest, and Oozing Ionizing Photons
Matthew J. Hayes, Alberto Saldana-Lopez, Annalisa Citro +5
We determine the spectroscopic properties of ~1000 ostensibly star-forming galaxies at redshifts (z=4-10) using prism spectroscopy from JWST/NIRSpec. With rest-wavelength coverage…
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…
A comprehensive metallicity analysis of J0332-3557: establishing a z ~ 4 anchor for direct gas metallicity and C/O abundance investigations
Annalisa Citro, Danielle A. Berg, Dawn K. Erb +4
We provide one of the most comprehensive metallicity studies at z 4 by analyzing the UV/optical HST photometry, and rest-frame VLT-FORS2 ultraviolet and VLT-XSHOOTER optical…
SDSS J1059+4251, a highly magnified z ~ 2.8 star-forming galaxy: ESI observations of the rest-frame UV spectrum
Annalisa Citro, Dawn K. Erb, Max Pettini +3
Detailed analyses of high-redshift galaxies are challenging due to their faintness, but this difficulty can be overcome with gravitational lensing, in which the magnification of th…

Spatially resolved signature of quenching in star-forming galaxies
Salvatore Quai, Lucia Pozzetti, Michele Moresco +5
Understanding when, how and where star formation ceased (quenching) within galaxies is still a critical subject in galaxy evolution studies. Taking advantage of the new methodology…
Discovery of a galaxy overdensity around a powerful, heavily obscured FRII radio galaxy at z=1.7: star formation promoted by large-scale AGN feedback?
