COS Observations of the Cosmic Web: A Search for the Cooler Components of a Hot, X-ray Identified Filament
Thomas Connor, Fakhri S. Zahedy, Hsiao-Wen Chen +3
In the local universe, a large fraction of the baryon content is believed to exist as diffuse gas in filaments. While this gas is directly observable in X-ray emission around clust…
A Giant Intragroup Nebula Hosting a Damped Lya Absorber at z=0.313
Hsiao-Wen Chen, Erin Boettcher, Sean D. Johnson +5
This paper reports the discovery of spatially-extended line-emitting nebula, reaching to ~100 physical kpc (pkpc) from a damped Lyα absorber (DLA) at z_DLA=0.313 along the sightlin…
Circumgalactic Gas and the Precipitation Limit
G. M. Voit, A. Babul, Iu. Babyk +15
During the last decade, numerous and varied observations, along with increasingly sophisticated numerical simulations, have awakened astronomers to the central role the circumgalac…
Probing IGM accretion onto faint Lyα emitters at z~2.8
Fakhri S. Zahedy, Michael Rauch, Hsiao-Wen Chen +3
(abridged) Observing the signature of accretion from the intergalactic medium (IGM) onto galaxies at z~3 requires the detection of faint (L<<L*) galaxies embedded in a filamentary…
Circumgalactic Pressure Profiles Indicate Precipitation-Limited Atmospheres for
G. M. Voit, M. Donahue, F. Zahedy +4
Cosmic gas cycles in and out of galaxies, but outside of galaxies it is difficult to observe except for the absorption lines that circumgalactic clouds leave in the spectra of back…
Characterizing circumgalactic gas around massive ellipticals at z~0.4 III. The galactic environment of a chemically-pristine Lyman limit absorber
Hsiao-Wen Chen, Sean D. Johnson, Lorrie A. Straka +7
This paper presents a study of the galactic environment of a chemically-pristine (<0.6% solar metallicity) Lyman Limit system (LLS) discovered along the sightline toward QSO SDSSJ1…
