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…
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_…
NuSTAR Observations of Intrinsically X-ray Weak Quasar Candidates: An Obscuration-Only Scenario
Chaojun Wang, B. Luo, W. N. Brandt +6
We utilize recent NuSTAR observations (co-added depth -120 ks) of PG , PG , and PHL 1811 to constrain their hard X-ray ( keV) weakness and…
On the relation between hard X-ray photon index versus accretion rate for super-Eddington accreting quasars
Jian Huang, Bin Luo, Pu Du +3
We investigate whether the hard X-ray photon index () versus accretion rate correlation for super-Eddington accreting quasars is different from that for sub-Eddington accreting…
