Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei
Francesco Shankar, David H. Weinberg, Christopher Marsden +25
The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…
On using inspiralling supermassive binary black holes in the PTA frequency band as standard sirens to constrain dark energy
Changshuo Yan, Wen Zhao, Youjun Lu
Supermassive binary black holes (SMBBHs) in galactic centers may radiate gravitational wave (GW) in the nano-Hertz frequency band, which are expected to be detected by pulsar timin…
Testing the relativistic Doppler boost hypothesis for supermassive binary black holes candidates via broad emission line profiles
Zihao Song, Junqiang Ge, Youjun Lu +1
Optical periodicity QSOs found by transient surveys are suggested to be sub-parsec supermassive binary black holes (BBHs). An intriguing interpretation for the periodicity of some…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
The Formation of a 70 Msun Black Hole at High Metallicity
K. Belczynski, R. Hirschi, E. A. Kaiser +7
A 70Msun BH was discovered in Milky Way disk in a long period and almost circular detached binary system (LB-1) with a high metallicity 8Msun B star companion. Current consensus on…
Effect of accreting tidally disrupted stars on the spin evolution of black holes
Xiaoxia Zhang, Youjun Lu, Zhu Liu
Accretion of tidally disrupted stars (TDSs) is expected to contribute significantly to the growth of massive black holes (MBHs) with mass in galactic centers.…
