The Impact of Scatter in the Galaxy UV Luminosity to Halo Mass Relation on Ly Visibility During the Epoch of Reionization
Lily R. Whitler, Charlotte A. Mason, Keven Ren +5
The reionization of hydrogen is closely linked to the first structures in the universe, so understanding the timeline of reionization promises to shed light on the nature of these…
Hubble Frontier Field Photometric Catalogues of Abell 370 and RXC J2248.7-4431: Multiwavelength photometry, photometric redshifts, and stellar properties
Marusa Bradac, Kuang-Han Huang, Marco Castellano +15
This paper presents multiwavelength photometric catalogues of the last two Hubble Frontier Fields (HFF), the massive galaxy clusters Abell 370 and RXC J2248.7-4431. The photometry…
Model-independent constraints on the hydrogen-ionizing emissivity at z>6
Charlotte A. Mason, Rohan P. Naidu, Sandro Tacchella +1
Modelling reionization often requires significant assumptions about the properties of ionizing sources. Here, we infer the total output of hydrogen-ionizing photons (the ionizing e…
Rapid Reionization by the Oligarchs: The Case for Massive, UV-Bright, Star-Forming Galaxies with High Escape Fractions
Rohan P. Naidu, Sandro Tacchella, Charlotte A. Mason +3
The protagonists of cosmic reionization remain elusive. Faint star-forming galaxies are leading candidates because they are numerous and may have significant ionizing photon escape…
Constraining Lyman-alpha spatial offsets at from VANDELS slit spectroscopy
A. Hoag, T. Treu, L. Pentericci +19
We constrain the distribution of spatially offset Lyman-alpha emission (Ly) relative to rest-frame ultraviolet emission in high redshift () Lyman-break galaxi…
The Brightest Galaxies at Cosmic Dawn from Scatter in the Galaxy Luminosity versus Halo Mass Relation
Keven Ren, Michele Trenti, Charlotte A. Mason
The Ultraviolet Luminosity Function (UVLF) is a key observable for understanding galaxy formation from cosmic dawn. There has been considerable debate on whether Schechter-like LFs…
