Deep XMM-Newton Observations of an X-ray Weak, Broad Absorption Line Quasar at

Jinyi Yang, Xiaohui Fan, Feige Wang +14

We report X-ray observations of the most distant known gravitationally lensed quasar, J0439+1634 at , which is also a broad absorption line (BAL) quasar, using the XMM-Newt…

Paving the Way for Euclid and JWST via Optimal Selection of High-z Quasars

Riccardo Nanni, Joseph F. Hennawi, Feige Wang +3

We introduce a probabilistic approach to select 6<z<8 quasar candidates for spectroscopic follow-up, which is based on density estimation in the high-dimensional space inhabited by…

Probing Early Super-massive Black Hole Growth and Quasar Evolution with Near-infrared Spectroscopy of 37 Reionization-era Quasars at 6.3 < z <= 7.64

Jinyi Yang, Feige Wang, Xiaohui Fan +18

We report the results of near-infrared spectroscopic observations of 37 quasars in the redshift range , including 32 quasars at , forming the largest quasar n…

Redshift identification of X-ray selected active galactic nuclei in the J1030 field: searching for large-scale structures and high-redshift sources

Stefano Marchesi, Marco Mignoli, Roberto Gilli +23

We publicly release the spectroscopic and photometric redshift catalog of the sources detected with Chandra in the field of the =6.3 quasar SDSS J1030+0525. This is currently th…

Chandra and Magellan/FIRE follow-up observations of PSO167-13: an X-ray weak QSO at

Fabio Vito, William Nielsen Brandt, Federica Ricci +19

The discovery of hundreds of QSOs in the first Gyr of the Universe powered by already grown SMBHs challenges our knowledge of SMBH formation. In particular, investigations of …

A Luminous Quasar at Redshift 7.642

Feige Wang, Jinyi Yang, Xiaohui Fan +20

Distant quasars are unique tracers to study the formation of the earliest supermassive black holes (SMBHs) and the history of cosmic reionization. Despite extensive efforts, only t…
