Evidence for Late-Time Feedback from the Discovery of Multiphase Gas in a Massive Elliptical at
Fakhri S. Zahedy, Hsiao-Wen Chen, Erin Boettcher +3
We report the first detection of multiphase gas within a quiescent galaxy beyond . The observations use the brighter image of doubly lensed QSO HE 00471756 to probe t…
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…
Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra
Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13
We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…
