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…
A Complete Census of Circumgalactic MgII at Redshift z<~ 0.5
Yun-Hsin Huang, Hsiao-Wen Chen, Stephen A. Shectman +5
We present a survey of MgII absorbing gas in the vicinity of 380 random galaxies, using 156 background quasi-stellar objects(QSOs) as absorption-line probes. The sample comprises 2…
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…
Spatially-resolved UV diagnostics of AGN feedback: radiation pressure dominates in a prototypical quasar-driven superwind
Jean Somalwar, Sean D. Johnson, Jonathan Stern +5
Galactic-scale winds driven by active galactic nuclei (AGN) are often invoked to suppress star formation in galaxy evolution models, but the mechanisms driving these outflows are h…
Observational nonstationarity of AGN variability: The only way to go is down!
Neven Caplar, Theodore Pena, Sean D. Johnson +1
To gain insights into long-term Active Galactic Nuclei (AGN) variability, we analyze an AGN sample from the Sloan Digital Sky Survey (SDSS) and compare their photometry with observ…
