Copious Amounts of Dust and Gas in a z=7.5 Quasar Host Galaxy
Bram Venemans, Fabian Walter, Roberto Decarli +10
We present IRAM/NOEMA and JVLA observations of the quasar J1342+0928 at z=7.54 and report detections of copious amounts of dust and [CII] emission in the interstellar medium (ISM)…
An 800-million-solar-mass black hole in a significantly neutral Universe at redshift 7.5
E. Bañados, B. P. Venemans, C. Mazzucchelli +15
Quasars are the most luminous non-transient objects known and as a result they enable studies of the Universe at the earliest cosmic epochs. Despite extensive efforts, however, the…
Physical properties of 15 quasars at
C. Mazzucchelli, E. Bañados, B. P. Venemans +21
Quasars are galaxies hosting accreting supermassive black holes; due to their brightness, they are unique probes of the early universe. To date, only few quasars have been reported…
Mapping the Lyman-Alpha Emission Around a z~6.6 QSO with MUSE: Extended Emission and a Companion at Close Separation
Emanuele P. Farina, Bram P. Venemans, Roberto Decarli +7
We utilize the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to search for extended Lyman-Alpha emission around the z~6.6 QSO J0305-3150. After careful…
Rapidly star-forming galaxies adjacent to quasars at redshifts exceeding 6
Roberto Decarli, Fabian Walter, Bram P. Venemans +11
The existence of massive ( solar masses) elliptical galaxies by redshift z~4 (when the Universe was 1.5 billion years old) necessitates the presence of galaxies with star-…
The compact, ~1 kpc host galaxy of a quasar at z=7.1
Bram Venemans, Fabian Walter, Roberto Decarli +6
We present ALMA observations of the [CII] fine structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (…
