Rest-Frame Optical Spectroscopy of Ten z 2 Weak Emission-Line Quasars
Ying Chen, Bin Luo, W. N. Brandt +7
We present near-infrared spectroscopy of ten weak emission-line quasars (WLQs) at redshifts of , obtained with the Palomar 200-inch Hale Telescope. WLQs are an exceptional…
XMM-Newton Observations of Two Archival X-ray Weak Type 1 Quasars: Obscuration Induced X-ray Weakness and Variability
Zijian Zhang, Bin Luo, W. N. Brandt +6
We report \hbox{XMM-Newton} observations of two examples of an unclassified type of \hbox{X-ray} weak quasars from the \citet{2020ApJ...900..141P} survey of \hbox{X-ray} weak quasa…
Extragalactic FXT Candidates Discovered by Chandra (2014-2022)
J. Quirola-Vásquez, F. E. Bauer, P. G. Jonker +9
Extragalactic fast X-ray transients (FXTs) are short flashes of X-ray photons of unknown origin that last a few minutes to hours. We extend the search for extragalactic FXTs from Q…
Radio AGN Selection and Characterization in Three Deep-Drilling Fields of the Vera C. Rubin Observatory Legacy Survey of Space and Time
Shifu Zhu, William N. Brandt, Fan Zou +4
The Australia Telescope Large Area Survey (ATLAS) and the VLA survey in the XMM-LSS/VIDEO deep field provide deep ( Jybeam) and high-resolution ( 4.5…
Strong and Rapid X-ray Variability of the Super-Eddington Accreting Quasar SDSS J081456.10+532533.5
Jian Huang, Bin Luo, W. N. Brandt +6
We report strong and rapid X-ray variability found from the super-Eddington accreting quasar SDSS J081456.10+532533.5 at . It has a black-hole mass of $2.7\times10^{7}{M_…
The Most Obscured AGNs in the XMM-SERVS Fields
Wei Yan, W. N. Brandt, Fan Zou +9
We perform X-ray spectral analyses to derive characteristics (e.g., column density, X-ray luminosity) of 10,200 active galactic nuclei (AGNs) in the XMM-Spitzer Extragalac…
