Black Hole - Bulge Relation of Quasars

摘要：

By using a sample of 33 nearby Seyfert galaxies, we obtain a tight corre lation between the inclination-corrected CO line width (FWHM(CO)/sini) and the bulge velocity dispersion (σ. We apply this new relation to nine high-redshift quasars with CO line detections and find that they are consistent with the local MBH - σ relation if their inclination angles are around 15o. The possible smaller inclinations of them are preferred because of their relatively greater likelihood of detection, and are also consistent with their relatively smaller CO line widths. In addition, we present a toy model to derive the black hole - bulge relation by considering two-direction starburst feedbacks to balance the dark matter halo gravity and the AGN winds.
