Title: Reverberation Mapping of AGNs 

Speaker: Jian-Min Wang (Institute of High Energy Physics, CAS) 

Time: 3 pm, May 17 (Thursday) 

Location: Lecture Hall, 3rd floor 

Abstract: AGNs are known to contain supermassive black holes (SMBHs) in galactic centres. Reverberation mapping is almost the unique technique to measure the fundamental  parameters of  SMBHs such as their mass and spin. Recently we developed a new technique to identify SMBH-binaries and measure the orbital parameters for the forthcoming gravitational waves. The talk will focus on the application of reverberation mapping of AGNs. 

Bio: Jian-Min Wang was graduated from Department of Applied Physics, National University of Defence Technology in 1987 and got PhD from University of Science and Technology of China in 1995. He worked in Tuebingen University under the support of A. v. Humboldt Foundation and in Kyoto University as a COE fellow. He was enlisted as Hundred Talent program and Distinguished Young Scholars of  NSFC. He is working on measurements of black hole mass through a large campaign of reverberation mapping of various kinds of active galactic nuclei. The scientific goals of the project aim at the application of super-Eddington accreting massive black holes to measurements of history of Universe expansion and discovery of close binaries of supermassive black holes for low frequency gravitational waves.
