No evidence for enhanced [OIII] 88um emission in a z~6 quasar compared to its companion starbursting galaxy

Fabian Walter, Dominik Riechers, Mladen Novak +14

We present ALMA band 8 observations of the [OIII] 88um line and the underlying thermal infrared continuum emission in the z=6.08 quasar CFHQS J2100-1715 and its dust-obscured starb…

The Discovery of A Luminous Broad Absorption Line Quasar at A Redshift of 7.02

Feige Wang, Jinyi Yang, Xiaohui Fan +18

Despite extensive efforts, only two quasars have been found at to date due to a combination of low spatial density and high contamination from more ubiquitous Galactic cool d…

Dust emission in an accretion-rate-limited sample of z>6 quasars

Bram Venemans, Roberto Decarli, Fabian Walter +9

We present Atacama Large Millimeter Array 1mm observations of the rest-frame far-infrared (FIR) dust continuum in 27 quasars at redshifts 6.0 < z < 6.7. We detect FIR emission at >…

No Evidence for Millimeter Continuum Source Overdensities in the Environments of Quasars

Jaclyn B. Champagne, Roberto Decarli, Caitlin M. Casey +11

Bright high-redshift quasars (), hosting supermassive black holes (), are expected to reside in massive host galaxies embedded within some of the…

A powerful radio-loud quasar at the end of cosmic reionization

Eduardo Banados, Chris Carilli, Fabian Walter +5

We present the discovery of the radio-loud quasar PSO J352.4034-15.3373 at z=5.84 pm 0.02. This quasar is the radio brightest source known, by an order of magnitude, at z~6 with a…

Chandra X-rays from the redshift 7.54 quasar ULAS J1342+0928

E. Bañados, T. Connor, D. Stern +9

We present a 45 ks Chandra observation of the quasar ULAS J1342+0928 at z=7.54. We detect 14.0^{+4.8}_{-3.7} counts from the quasar in the observed-frame energy range 0.5-7.0 keV (…
