Abstract (from CDS):

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 x108 M; NGC 3607, MBH= 1.2+0.4–0.4x108 M; NGC 4026, MBH= 2.1+0.7–0.4x108 M; and NGC 5576, MBH = 1.8+0.3–0.4x108 M, all significantly excluding MBH = 0. For NGC 3945, MBH= 9+17–21x106 M, which is significantly below predictions from M-σ and M-L relations and consistent with M BH= 0, though the presence of a double bar in this galaxy may present problems for our axisymmetric code.
