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…
A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at
Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +22
Gas flows between galaxies and the circumgalactic medium (CGM) play a central role in galaxy evolution and can become observable as giant nebulae when illuminated by the quasars. W…
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…
High-definition imaging of a filamentary connection between a close quasar pair at z=3
Davide Tornotti, Michele Fumagalli, Matteo Fossati +16
Filaments connecting halos are a long-standing prediction of cold dark matter theories. We present a detection of the cosmic web emission connecting two quasar-host galaxies at red…
The MUSE Ultra Deep Field (MUDF) VII. Probing high-redshift gas structures in the surroundings of ALMA-identified massive dusty galaxies
A. Pensabene, M. Galbiati, M. Fumagalli +12
We present new ALMA continuum and spectral observations of the MUSE Ultra Deep Field (MUDF), a arcmin region with ultradeep multiwavelength imaging and spectroscopy…
