Low heat conduction in white dwarf boundary layers?
F. K. Liu, F. Meyer, E. Meyer-Hofmeister +1
X-ray spectra of dwarf novae in quiescence observed by Chandra and XMM-Newton provide new information on the boundary layers of their accreting white dwarfs. Comparison of observat…
Tidal Disruption of Stellar Objects by Hard Supermassive Black Hole Binaries
Xian Chen, F. K. Liu, John Magorrian
Supermassive black hole binaries (SMBHBs) are expected by the hierarchical galaxy formation model in CDM cosmology. There is some evidence in the literature for SMBHBs in AGNs,…
Evolution of Supermassive Black Hole Binary and Acceleration of Jet Precession in Galactic Nuclei
F. K. Liu, X. Chen
Supermassive black hole binary (SMBHB) is expected with the hierarchical galaxy formation model. Currently, physics processes dominating the evolution of a SMBHB are unclear. An in…
Weighing black holes in radio-loud AGNs
Xue-Bing Wu, F. K. Liu, R. Wang +2
Because of the contamination of jets, using the size -- continuum luminosity relation can overestimate the broad line region (BLR) size and black hole mass for radio-loud AGNs. We…
Harmonic QPOs and Thick Accretion Disk Oscillations in BL Lac Object AO 0235+164
F. K. Liu, G. Zhao, Xue-Bing Wu
Periodic outbursts are observed in many AGNs and usually explained with a supermassive black hole binary (SMBHB) scenario. However, multiple periods are observed in some AGNs and c…
Black hole mass and accretion rate of Active Galactic Nuclei
Xue-Bing Wu, F. K. Liu, R. Wang +2
The determination of the central black hole mass is crucial to the understanding of AGN physics. In this paper we briefly review some methods that are currently used to estimate th…
