KODIAQ-Z: Metals and Baryons in the Cool Intergalactic and Circumgalactic Gas at 2.2<z<3.6
Nicolas Lehner, Claire Kopenhafer, John O'Meara +8
We present the KODIAQ-Z survey aimed to characterize the cool, photoionized gas at 2.2<z<3.6 in 202 HI-selected absorbers with 14.6<log N(HI)<20, i.e., the gaseous interface betwee…
Spectroscopic Confirmation of a Protocluster at with a High Fraction of Quiescent Galaxies
Ian McConachie, Gillian Wilson, Ben Forrest +10
We report the discovery of MAGAZ3NE J095924+022537, a spectroscopically-confirmed protocluster at around a spectroscopically-confirmed -quiesc…
The CGM Survey: Circumgalactic O VI from dwarf to massive star-forming galaxies
K. Tchernyshyov, J. K. Werk, M. C. Wilde +9
We combine 126 new galaxy-O VI absorber pairs from the CGM survey with 123 pairs drawn from the literature to examine the simultaneous dependence of the column density of O VI…
Lyman Continuum Galaxy Candidates in COSMOS
Laura J. Prichard, Marc Rafelski, Jeff Cooke +11
Star-forming galaxies are the sources likely to have reionized the universe. As we cannot observe them directly due to the opacity of the intergalactic medium at , we st…
SILVERRUSH. XI. Intensity Mapping for Lya Emission Extending over comoving kpc around LAEs with Subaru HSC-SSP and CHORUS Data
Shotaro Kikuchihara, Yuichi Harikane, Masami Ouchi +14
We conduct intensity mapping to probe for extended diffuse Ly emission around Ly emitters (LAEs) at , exploiting very deep ( mag at ) and large-area ($\…
The HI Column Density Distribution of the Galactic Disk and Halo
David M. French, Andrew J. Fox, Bart P. Wakker +8
We present a census of neutral gas in the Milky Way disk and halo down to limiting column densities of (HI) cm using measurements of HI Lyman-series absorpti…
