The Grism Lens-Amplified Survey from Space (GLASS). XII. Spatially Resolved Galaxy Star Formation Histories and True Evolutionary Paths at z > 1
L. E. Abramson, A. B. Newman, T. Treu +12
Modern data empower observers to describe galaxies as the spatially and biographically complex objects they are. We illustrate this through case studies of four, systems…
RELICS: Strong Lens Models for Five Galaxy Clusters From the Reionization Lensing Cluster Survey
Catherine Cerny, Keren Sharon, Felipe Andrade-Santos +31
Strong gravitational lensing by galaxy clusters magnifies background galaxies, enhancing our ability to discover statistically significant samples of galaxies at z>6, in order to c…
The Reionization Lensing Cluster Survey (RELICS) and the Brightest High-z Galaxies
Brett Salmon, Dan Coe, Larry Bradley +31
Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy population…
The Universe is Reionizing at z~7: Bayesian Inference of the IGM Neutral Fraction Using Ly Emission from Galaxies
Charlotte A. Mason, Tommaso Treu, Mark Dijkstra +5
We present a new flexible Bayesian framework for directly inferring the fraction of neutral hydrogen in the intergalactic medium (IGM) during the Epoch of Reionization (EoR, z~6-10…
HST Grism Observations of a Gravitationally Lensed Redshift 10 Galaxy
Austin Hoag, Maruša Bradač, Gabriel B. Brammer +11
We present deep spectroscopic observations of a Lyman-break galaxy candidate (hereafter MACS1149-JD) at with the Space Telescope () WFC3/…
Spectroscopic confirmation of an ultra-faint galaxy at the epoch of reionization
Austin Hoag, Maruša Bradač, Michele Trenti +11
Within one billion years of the Big Bang, intergalactic hydrogen was ionized by sources emitting ultraviolet and higher energy photons. This was the final phenomenon to globally af…
