标题： Accurate AGN black hole masses and the scatter in the M_{bh} - L_{bulge} relationship

摘要： 给出了一个新的经验公式，用于根据 Hβ 速度弥散和 5100 埃处的连续谱光度来估计活动星系核（AGN）中的黑洞质量。该公式通过回声映射和恒星动力学方法估算的黑洞质量进行了校准。由此得到的质量估计值与回声映射和恒星动力学方法的估计值一样准确。新的质量估计表明，在高光度星系中 M-{bh}-L_{隆起}关系几乎没有散射，而在低质量星系中散射显著增加。 显示英文摘要

摘要： A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation-mapping and stellar-dynamical estimates of black hole masses. The resulting mass estimates are as accurate as reverberation-mapping and stellar-dynamical estimates. The new mass estimates show that there is very little scatter in the M_{bh} - L_{bulge} relationship for high-luminosity galaxies, and that the scatter increases substantially in lower-mass galaxies.
