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…
Resolved galactic superwinds reconstructed around their host galaxies at z>3
Mandy C. Chen, Hsiao-Wen Chen, Max Gronke +2
This paper presents a detailed analysis of two giant Lyman-alpha (Lya) arcs detected near known galaxies at z=3.038 and z=3.754 lensed by the massive cluster MACS 1206 (z=0.44). Th…
Geometric Support for Dark Matter by an Unaligned Einstein Ring in Abell 3827
Mandy C. Chen, Tom Broadhurst, Jeremy Lim +4
The non-detection of dark matter (DM) particles in increasingly stringent laboratory searches has encouraged alternative gravity theories where gravity is sourced only from visible…
A Likely Super Massive Black Hole Revealed by its Einstein Radius in Hubble Frontier Fields Images
Mandy C. Chen, Tom Broadhurst, Jeremy Lim +4
At cosmological distances, gravitational lensing can provide a direct measurement of supermassive black hole (SMBH) masses irrespective of their luminosities. Here, we directly est…
