A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
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…
(SHERRY) JCMT-SCUBA2 High Redshift Bright Quasar Survey -- II: the environment of z~6 quasars in sub-millimeter band
Qiong Li, Ran Wang, Xiaohui Fan +14
The formation of the first supermassive black holes is expected to have occurred in some most pronounced matter and galaxy overdensities in the early universe. We have conducted a…
Optical and near-infrared spectroscopy of quasars at : public data release and composite spectrum
Silvia Onorato, Joseph F. Hennawi, Jan-Torge Schindler +18
We present optical and near-infrared (NIR) spectroscopic observations for a sample of quasars at with absolute magnitudes at à in the range $-28.82…
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…
ALMA 360 pc high-frequency observations reveal warm dust in the center of a quasar
Romain A. Meyer, Fabian Walter, Fabio Di Mascia +3
The temperature of the cold dust in z>6 galaxies is a potential tracer of Active Galactic Nucleus (AGN) and stellar feedback, and is the dominant source of uncertainty in inferring…
