An Extremely-High Velocity Outflow in SMSS J2157-3602, the most luminous quasar in the first 1.3 Gyr
Giustina Vietri, Paola Rodriguez Hidalgo, Amy Rankine +16
We report the discovery of an extremely high-velocity outflow (EHVO) in the most luminous ( 2.29 10 erg/s) QSO, SMSS J2157-3602, at z=4.692. Comb…
The WISSH quasar project. XII. X-ray view of the most luminous quasi-stellar objects at Cosmic Noon
C. Degli Agosti, C. Vignali, E. Piconcelli +25
To improve our knowledge of nuclear emission in luminous QSOs at Cosmic Noon, we studied the X-ray emission of the WISE/SDSS-selected hyper-luminous (WISSH) QSO sample: 85 broad-li…
Selection of optically variable active galactic nuclei via a random forest algorithm
Demetra De Cicco, Gaetano Zazzaro, Stefano Cavuoti +5
Context. A defining characteristic of active galactic nuclei (AGN) that distinguishes them from other astronomical sources is their stochastic variability, which is observable acro…
