Seven \"blue outliers\" with [O III] blueshifted by more than 250 \\kms are found. A strong correlation between the [O III] blueshift and the Eddington ratio is found for these seven \"blue outliers\". For the entire sample, we found a modest correlation between the blueshift and the linewidth of the narrow component of the [O III] line. The reflected profile of [O III] indicates two kinematically and physically distinct regions. The [O III] linewidth depends not only on the bulge stellar gravitational potential, but also on the central black hole potential.", "revisions": [ { "version": "v1", "updated": "2005-08-26T03:32:56.000Z" } ], "analyses": { "keywords": [ "emission line", "central black hole potential", "blue outliers", "bulge stellar gravitational potential", "radial velocity difference" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 690829, "adsabs": "2005astro.ph..8570B" } } }
