X-ray Observations of a [C II]-bright, z=6.59 Quasar/Companion System
Thomas Connor, Eduardo Bañados, Chiara Mazzucchelli +7
We present deep Chandra observations of PSO J231.657620.8335, a quasar at redshift z=6.59 with a nearby ( proper kpc) companion galaxy. ALMA observed both the quasar an…
No Redshift Evolution in the Broad Line Region Metallicity up to z=7.54: Deep NIR Spectroscopy of ULAS J1342+0928
Masafusa Onoue, Eduardo Bañados, Chiara Mazzucchelli +12
We present deep (9 hours) Gemini-N/GNIRS near-infrared spectroscopic observations of ULAS J1342+0928, a luminous quasar at z=7.54. Various broad emission lines were detected, as we…
Pōniuā'ena: A Luminous Quasar Hosting a 1.5 Billion Solar Mass Black Hole
Jinyi Yang, Feige Wang, Xiaohui Fan +16
We report the discovery of a luminous quasar, J1007+2115 at ("Pōniuā'ena"), from our wide-field reionization-era quasar survey. J1007+2115 is the second quasar now known…
A Significantly Neutral Intergalactic Medium Around the Luminous z=7 Quasar J0252-0503
Feige Wang, Frederick B. Davies, Jinyi Yang +14
Luminous quasars provide direct probes of the evolution of supermassive black holes (SMBHs) and the intergalactic medium (IGM) during the epoch of reionization (EoR). The L…
Discovery of intergalactic bridges connecting two faint quasars
Fabrizio Arrigoni Battaia, Aura Obreja, J. Xavier Prochaska +6
We use MUSE/VLT to conduct a survey of physical quasar pairs at close separation with a fast observation strategy. Our aim is twofold: (i) explore the Ly glow around th…
X-ray Observations of a Quasar/Galaxy Merger
Thomas Connor, Eduardo Bañados, Daniel Stern +7
Quasars at early redshifts () with companion galaxies offer unique insights into the growth and evolution of the first supermassive black holes. Here, we report on a 150 ks…
