Staring at the Shadows of Archaic Galaxies: Damped Ly and Metal Absorbers toward a Young Weak-line Quasar
Irham Taufik Andika, Knud Jahnke, Eduardo Bañados +6
We characterize the Ly halo and absorption systems toward PSO J083+11, a unique weak-line quasar, using Gemini/GNIRS, Magellan/FIRE, and VLT/MUSE data. Strong absorpt…
Random Forests as a viable method to select and discover high redshift quasars
Lukas Wenzl, Jan-Torge Schindler, Xiaohui Fan +9
We present a method of selecting quasars up to redshift 6 with random forests, a supervised machine learning method, applied to Pan-STARRS1 and WISE data. We find that, t…
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…
A significant excess in major merger rate for AGNs with the highest Eddington ratios at z<0.2
V. Marian, K. Jahnke, I. Andika +16
Observational studies are increasingly finding evidence against major mergers being the dominant mechanism responsible for triggering AGN. After studying the connection between maj…
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…
