Enhanced X-ray Emission from the Most Radio-Powerful Quasar in the Universe's First Billion Years
Thomas Connor, Eduardo Bañados, Daniel Stern +8
We present deep (265 ks) Chandra X-ray observations of PSO J352.403415.3373, a quasar at z=5.831 that, with a radio-to-optical flux ratio of R>1000, is one of the radio-loudest…
The discovery of a highly accreting, radio-loud quasar at z=6.82
Eduardo Banados, Chiara Mazzucchelli, Emmanuel Momjian +17
Radio sources at the highest redshifts can provide unique information on the first massive galaxies and black holes, the densest primordial environments, and the epoch of reionizat…
The Quasar Feedback Survey: Discovering hidden Radio-AGN and their connection to the host galaxy ionised gas
M. E. Jarvis, C. M. Harrison, V. Mainieri +18
We present the first results from the Quasar Feedback Survey, a sample of 42 z<0.2, [O III] luminous AGN (L[O III]>10^42.1 ergs/s) with moderate radio luminosities (i.e. L(1.4GHz)>…
A Luminous Quasar at Redshift 7.642
Feige Wang, Jinyi Yang, Xiaohui Fan +20
Distant quasars are unique tracers to study the formation of the earliest supermassive black holes (SMBHs) and the history of cosmic reionization. Despite extensive efforts, only t…
Dating individual quasars with the HeII proximity effect
Gábor Worseck, Ilya S. Khrykin, Joseph F. Hennawi +2
Constraints on the time-scales of quasar activity are key to understanding the formation and growth of supermassive black holes (SMBHs), quasar triggering mechanisms, and possible…
