我们报告了基于哈勃太空望远镜 (HST) 的太空望远镜成像摄谱仪和宽视场行星相机 2 观测以及轴对称、三积分、史瓦西轨道库运动学模型对中心黑洞质量的五项新测量。我们选择了速度弥散范围较窄的星系样本，这些样本涵盖了一系列星系参数（包括哈勃类型和核心/幂律表面密度剖面），我们希望能够根据 M-σ 关系预测的黑洞质量值来解析星系的影响范围。我们找到以下星系的质量：NGC 3585，MBH = 3.4+1.5−0.6 × 108 M☉； NGC 3607，MBH = 1.2+0.4−0.4 × 108 M☉； NGC 4026，MBH = 2.1+0.7−0.4 × 108 M☉；和 NGC 5576，MBH = 1.8+0.3−0.4 × 108 M☉，均显着排除 MBH = 0。对于 NGC 3945，MBH = 9+17−21 × 106 M☉，显着低于 M–σ 和 M–L 关系的预测，并与 MBH = 0 一致，尽管该星系中双棒的存在可能会给我们的轴对称带来问题代码。
We report five new measurements of central black hole masses based on Space Telescope Imaging Spectrograph and Wide Field Planetary Camera 2 observations with the Hubble Space Telescope (HST) and on axisymmetric, three-integral, Schwarzschild orbit-library kinematic models. We selected a sample of galaxies within a narrow range in velocity dispersion that cover a range of galaxy parameters (including Hubble type and core/power-law surface density profile) where we expected to be able to resolve the galaxy's sphere of influence based on the predicted value of the black hole mass from the M–σ relation. We find masses for the following galaxies: NGC 3585, MBH = 3.4+1.5−0.6 × 108 M☉; NGC 3607, MBH = 1.2+0.4−0.4 × 108 M☉; NGC 4026, MBH = 2.1+0.7−0.4 × 108 M☉; and NGC 5576, MBH = 1.8+0.3−0.4 × 108 M☉, all significantly excluding MBH = 0. For NGC 3945, MBH = 9+17−21 × 106 M☉, which is significantly below predictions from M–σ and M–L relations and consistent with MBH = 0, though the presence of a double bar in this galaxy may present problems for our axisymmetric code.
