We present a search for metal absorption line systems at the highest redshifts to date using a deep (30h) VLT/X-Shooter spectrum of the z = 7.084 quasi-stellar object (QSO) ULAS J1…
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 (…
Planck intermediate results. XXXIX. The Planck list of high-redshift source candidates
Planck Collaboration, P. A. R. Ade, N. Aghanim +186
The Planck mission, thanks to its large frequency range and all-sky coverage, has a unique potential for systematically detecting the brightest, and rarest, submillimetre sources o…
