The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5
Marie Wisz, Marc Rafelski, Grecco Oyarzun +10
Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conte…
ALMA and JWST Imaging of Quasars: No Spatial Position Offset Observed Between Quasars and Their Host Galaxies
Aurora Wilde, Marcel Neeleman, Romain Meyer +4
We present a study determining the spatial offset between the position of the supermassive black hole (as traced through their broad line regions) and the host galaxy in six $z > 6…
A [CII]-158-micron Survey of DLA galaxies at z~4: Observations of Dense and Metal-Enriched Neutral Gas within the Circumgalactic Medium of Star-Forming Galaxies
Marcel Neeleman, Nissim Kanekar, J. Xavier Prochaska +2
We present a survey undertaken with the Atacama Large Millimeter/submillimeter Array (ALMA) to study the galaxies associated with a representative sample of 16 damped Ly-alpha abso…
Kiloparsec-Scale Alignment of a Radio Jet with Cool Gas and Dust in a z~6 Quasar
Fabian Walter, Eduardo Banados, Chris Carilli +11
We present high-angular resolution (0.068", ~400pc) ALMA imaging of the [CII] line and dust continuum emission of PSO J352.4034-15.3373, a radio-loud quasar at z=5.83. The observat…
The Qz5 Survey (I): How the HI Mass Density of the Universe Evolves With Cosmic Time
Grecco A. Oyarzún, Marc Rafelski, Lise Christensen +9
We report that the neutral hydrogen (HI) mass density of the Universe () increases with cosmic time since , peaks at , and then decreases toward $z \si…
A massive HI-absorption-selected galaxy at
Balpreet Kaur, Nissim Kanekar, Marcel Neeleman +4
We use the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) to detect , , and rest-frame 349-GHz continuu…
