The X-ray properties of quasars: no evident evolution of accretion physics in the first Gyr of the Universe
Fabio Vito, William Nielsen Brandt, Franz Erik Bauer +10
X-ray emission from QSOs has been used to assess SMBH accretion properties up to ~6. However, at only ~15 QSOs are covered by sensitive X-ray observations, preventing a st…

Discovery of the first heavily obscured QSO candidate at in a close galaxy pair
Fabio Vito, William Nielsen Brandt, Franz Erik Bauer +14
While theoretical arguments predict that most of the early growth of supermassive black holes (SMBHs) happened during heavily obscured phases of accretion, current methods used for…

SDSS J075101.42+291419.1: A Super-Eddington Accreting Quasar with Extreme X-ray Variability
Hezhen Liu, B. Luo, W. N. Brandt +6
We report the discovery of extreme X-ray variability in a type 1 quasar: SDSS J. It has a black hole mass of measured from reverber…
