DESCRIPTION
The relation between bulge and SMBH and its evolution. M-L and M-sigma relation. In local quiescent galaxies(Kormendy 1993a, Kormendy & Richstone 1995 Gebhardt et al., 2000). 更多的研究: AGN 中此关系仍成立 (McLure and Dunlop, 2002; Nelson et al., 2004). M-L 的弥散很大部分由观测造成 (0304274) - PowerPoint PPT Presentation
