There is a tight M−σ relation in nearby inactive galaxies. Nearby radio-quiet AGNs also followed this relation. In order to investigate whether radio-loud AGNs and NLS1s follow this relation or not, we estimated their central black hole masses from Hβ and the bulge velocity dispersions from [O III] linewidth. We found that radio-loud AGNs and NLS1s seemed to deviate from this relation.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
