Discovery of a damped Ly absorber originating in a spectacular interacting dwarf galaxy pair at
Erin Boettcher, Neeraj Gupta, Hsiao-Wen Chen +18
We present the discovery of neutral gas detected in both damped Ly absorption (DLA) and HI 21-cm emission outside of the stellar body of a galaxy, the first such detection in th…
The Cosmic Ultraviolet Baryon Survey (CUBS) IV: The Complex Multiphase Circumgalactic Medium as Revealed by Partial Lyman Limit Systems
Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen +18
We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density discovered at…
The Cosmic Ultraviolet Baryon Survey (CUBS) -- III. Physical properties and elemental abundances of Lyman limit systems at
Fakhri S. Zahedy, Hsiao-Wen Chen, Thomas M. Cooper +18
(Abridged) We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at discovered withi…
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…
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…
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…
