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…
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…
The MUSE Ultra Deep Field: A 5 Mpc stretch of the z 4 cosmic web revealed in emission
Davide Tornotti, Michele Fumagalli, Matteo Fossati +7
We detect Ly emission from a ~5 Mpc-long (comoving) portion of the cosmic web hosting an overdensity () of 19 Ly emitters (LAEs) at within the MU…
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…
