A search for dust and molecular gas in enormous Ly nebulae at
Roberto Decarli, Fabrizio Arrigoni-Battaia, Joseph F. Hennawi +3
Enormous Ly nebulae, extending over 300-500\,kpc around quasars, represent the pinnacle of galaxy and cluster formation. Here we present IRAM Plateau de Bure Interferometer obse…
A High-Resolution View of Fast Radio Burst Host Environments
Alexandra G. Mannings, Wen-fai Fong, Sunil Simha +11
We present Hubble Space Telescope (HST/WFC3) ultraviolet and infrared observations of eight fast radio burst (FRB) host galaxies with sub-arcsecond localizations, including the hos…
New Evidence for Extended HeII Reionization at z>3.5 from HeII Lyman Alpha and Beta Transmission Spikes
Kirill Makan, Gábor Worseck, Frederick B. Davies +3
We present new high-resolution (R~14,000) spectra of the two brightest HeII-transparent quasars in the far-UV (FUV) at z>3.5, HE2QSJ2311-1417 (z=3.70) and HE2QSJ1630+0435 (z=3.81),…
The COS Absorption Survey of Baryon Harbors: Unveiling the Physical Conditions of Circumgalactic Gas through Multiphase Bayesian Ionization Modeling
Karl J. Haislmaier, Todd M. Tripp, Neal Katz +4
Quasar absorption systems encode a wealth of information about the abundances, ionization structure, and physical conditions in intergalactic and circumgalactic media. Simple (ofte…
The Third Data Release of the KODIAQ Survey
John M. O'Meara, Nicolas Lehner, J. Christopher Howk +1
We present and make publicly available the third data release (DR3) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ) survey. KODIAQ DR3 consists of a…
High Molecular Gas Masses in Absorption-selected Galaxies at
Nissim Kanekar, J. Xavier Prochaska, Marcel Neeleman +5
We have used the Atacama Large Millimeter/submillimeter Array (ALMA) to carry out a search for CO (32) or (43) emission from the fields of 12 high-metallicity ([M/H]~$\geq -0…
