Reverberation mapping of active galactic nuclei for black hole mass: current, future and applications


Reverberation mapping (RM) as a powerful tool measures time lags of broad emission lines with respect to varying continuum for kinematics and structure of broad-line regions in active galactic nuclei (AGNs) and leads to the well-known R-L relation. This time-domain technique has been advanced for more than 40 years for accurate measurements of supermassive black hole mass, in particular, velocity-resolved, 2-dimension maps, polarization and MCMC are applied nowadays for AGN physics. In this seminar,  I briefly introduce the RM technique, current results of several campaigns and applications. We have performed  four years of spectroscopic monitoring super-Eddington accreting AGNs through the Lijiang 2.4m telescope. Results of this campaign will be reported, such as, Hbeta shorter lags, Fe II reverberation, BLR fundamental plane and saturated luminosity of super-Eddington accretion as standard candles. Prospect of future observations is overviewed.
