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…
The z=7.54 Quasar ULAS J1342+0928 Is Hosted by a Galaxy Merger
Eduardo Banados, Mladen Novak, Marcel Neeleman +9
We present ALMA 0.28"x0.20" (1.4kpc x 1.0kpc) resolution observations of the [CII] 158um line and underlying dust continuum in the host galaxy of the most distant quasar currently…
The Evolution of O I over 3.2 < z < 6.5: Reionization of the Circumgalactic Medium
George D. Becker, Max Pettini, Marc Rafelski +11
We present a survey for metal absorption systems traced by neutral oxygen over . Our survey uses Keck/ESI and VLT/X-Shooter spectra of 199 QSOs with redshifts up to…
Resolved [CII] Emission from z>6 Quasar Host -- Companion Galaxy Pairs
Marcel Neeleman, Eduardo Bañados, Fabian Walter +10
We report on ~0.35"(~2 kpc) resolution observations of the [CII] and dust continuum emission from five z>6 quasar host-companion galaxy pairs obtained with the Atacama Large Millim…
An ALMA multi-line survey of the interstellar medium of the redshift 7.5 quasar host galaxy J1342+0928
Mladen Novak, Eduardo Banados, Roberto Decarli +9
We use ALMA observations of the host galaxy of the quasar ULAS-J1342+0928 at z=7.54 to study the dust continuum and far infrared lines emitted from its interstellar medium. The Ray…
