　　Title: Measuring the most massive black holes in the Universe

　　Speaker: Dr. Shai Kaspi

　　Affiliation: Tel Aviv University, Israel　

　　Time:  Oct 21, 2013 (Monday) 15:30 p.m.

　　Venue: Meeting Room 401 (Main Building)

　　Abstract:　

　　In the past three decades reverberation mapping has been used to

　　measure the size of the BLR and the black hole mass of about 50 AGNs.

　　However, the luminosity of these AGNs is limited to the range of

　　10^42 to 10^46 ergs/sec while there are AGNs as bright as 10^49 ergs/sec.

　　Thus, reverberation mapping studies are missing three orders of magnitude

　　in luminosity. In my talk I will describe the reverberation mapping method

　　and our attempts done over the past years to carry out reverberation mapping

　　studies of luminous high red-shift quasars in that missing luminosity range.
