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.…
On the Mean Radiative Efficiency of Accreting Massive Black Holes in AGNs And QSOs
Xiaoxia Zhang, Youjun Lu
Radiative efficiency is an important physical parameter that describes the fraction of accretion material converted to radiative energy for accretion onto massive black holes (MBHs…
On Constraining the Growth History of Massive Black Holes via Their Distribution on the Spin-Mass Plane
Xiaoxia Zhang, Youjun Lu
The spin distribution of massive black holes (MBHs) contains rich information on the MBH growth history. In this paper, we investigate the spin evolution of MBHs by assuming that e…
