The Cosmic Ultraviolet Baryon Survey (CUBS) II: Discovery of an H-Bearing DLA in the Vicinity of an Early-Type Galaxy at z = 0.576
Erin Boettcher, Hsiao-Wen Chen, Fakhri S. Zahedy +18
We report the serendipitous detection of an H-bearing damped Lyman- absorber at z = 0.576 in the spectrum of the QSO J0111-0316 in the Cosmic Ultraviolet Baryon Survey. Sp…
The Cosmic Ultraviolet Baryon Survey (CUBS) I. Overview and the diverse environments of Lyman limit systems at z<1
Hsiao-Wen Chen, Fakhri S. Zahedy, Erin Boettcher +19
We present initial results from the Cosmic Ultraviolet Baryon Survey (CUBS). CUBS is designed to map diffuse baryonic structures at redshift z<~1 using absorption-line spectroscopy…
Stellar mass measurements in Abell 133 with Magellan / IMACS
S. Starikova, A. Vikhlinin, A. Kravtsov +4
We present the analysis of deep optical imaging of the galaxy cluster Abell 133 with the IMACS instrument on Magellan. Our multi-band photometry enables stellar mass measurements i…
LATIS: The Ly Tomography IMACS Survey
Andrew B. Newman, Gwen C. Rudie, Guillermo A. Blanc +15
We introduce LATIS, the Ly Tomography IMACS Survey, a spectroscopic survey at Magellan designed to map the z=2.2-2.8 intergalactic medium (IGM) in three dimensions by observing…
