Testing Blandford-Znajek mechanism in black hole hyperaccretion flows for long-duration gamma-ray bursts

Mei Du, Shuang-Xi Yi, Tong Liu +2

Long-duration gamma-ray bursts (GRBs) are generally related to the core-collapse of massive stars. In the collapsar scenario, a rotating stellar-mass black hole (BH) surrounded by…

Chandra Detection of Three X-ray Bright Quasars at z>5

Jiang-Tao Li, Feige Wang, Jinyi Yang +8

We report Chandra detection of three UV bright radio quiet quasars at . We have collected a sufficient number of photons to extract an X-ray spectrum of each quasar to m…

Extended X-ray emission from the z=4.26 radio galaxy 4C 63.20

Kate Napier, Adi Foord, Elena Gallo +5

We report on deep Chandra X-ray Telescope imaging observations of 4C 63.20, one of the few known radio galaxies at z>3.5. The X-ray counterpart is resolved into a core plus two off…

The -- relation and corona-disk-jet connection in optically selected radio-loud quasars

S. F. Zhu, W. N. Brandt, B. Luo +3

Radio-loud quasars (RLQs) are more X-ray luminous than predicted by the X-ray-optical/UV relation (i.e. ) for radio-quiet quasars (RQQs). The e…

On the Power to Constrain the Accretion History of Massive Black Holes via Spin Measurements by Upcoming X-Ray Telescopes

Xiaoxia Zhang, Youjun Lu, Dandan Wang +1

The spin distribution of massive black holes (MBHs) contains rich information on their assembly history. However, only limited information can be extracted from currently available…
