Beneath the Surface: >85% of z>5.9 QSOs in Massive Host Galaxies are UV-Faint
R. J. Bouwens, E. Banados, R. Decarli +20
We use [CII] observations of a large QSO sample to segregate sources by host galaxy mass, aiming to identify those in the most massive hosts. [CII] luminosity, a known tracer of mo…

Discovery and characterization of 25 new quasars at 4.6 < z < 6.9 from wide-field multi-band surveys
Silvia Belladitta, Eduardo Bañados, Zhang-Liang Xie +18
Luminous quasars at provide key insights into the early Universe. Their rarity necessitates wide-field multi-band surveys to efficiently separate them from the main astrophys…

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…
