We have carried out the first HST long-slit observations of a gaseous disk around a candidate super-massive black hole. The results of this study on the kinematics of the gaseous disk in M 87 are a considerable improvement in both spatial resolution and accuracy over previous observations and requires a projected mass of MBH (sin i)2=(2.0±0.5)×109 M⊙ (MBH=3.2×109 M⊙ for a disk inclination i=52°) concentrated within a sphere whose radius is less than 0″.05 (3.5 pc) to explain the observed… 
The Supermassive Black Hole in M84 Revisited
The mass of the central black hole in the giant elliptical galaxy M84 has previously been measured by two groups using the same observations of emission-line gas with the Space Telescope Imaging
Gas kinematics and the black hole mass at the center of the radio galaxy NGC 4335
We investigate the kinematics of the central gas disk of the radio-loud elliptical galaxy NGC 4335, derived from Hubble Space Telescope (HST) long-slit spectroscopic observations of Hα + [N II] along

Abstract At less than 4 Mpc distance the radio galaxy NGC 5128 (Centaurus A) is the prime example to study the supermassive black hole and its influence on the environment in great detail. To model
The nuclear disk in M 87: A review
The disk in the center of M 87 is a prototype for gas orbiting a massive central object. Three sets of HST + COSTAR FOS and FOC observations provide strong evidence that the nuclear disk in M 87 is
Isophotal analysis of M87, using data from the Advanced Camera for Surveys, reveals a projected displacement of 6.8 +/- 0.8 pc (similar to 0 ''.1) between the nuclear point source (presumed to be the
Is There Really a Black Hole at the Center of NGC 4041? Constraints from Gas Kinematics*
We present Space Telescope Imaging Spectrograph spectra of the Sbc spiral galaxy NGC 4041, which were used to map the velocity field of the gas in its nuclear region. We detect the presence of a
A Search for Molecular Gas in the Nucleus of M87 and Implications for the Fueling of Supermassive Black Holes
Supermassive black holes in giant elliptical galaxies are remarkably faint given their expected accretion rates. This motivates models of radiatively inefficient accretion due to either ion-electron
The supermassive black hole in the Seyfert 2 galaxy NGC 5252
We present results from HST/STIS long-slit spectroscopy of the gas motions in the nuclear region of the Seyfert 2 galaxy NGC 5252. The observed velocity field is consistent with gas in regular
Measuring supermassive black holes with gas kinematics. II. The LINERs IC 989 , NGC 5077 , and NGC 6500
We present results from a kinematical study of the gas in the nucleus of a sample of three LINER galaxies, obtained from archival HST/STIS long-slit spectra. We found that, while for the elliptical
Measuring the mass of the central black hole in the bulgeless galaxy NGC 4395 from gas dynamical modeling
NGC 4395 is a bulgeless spiral galaxy, harboring one of the nearest known type 1 Seyfert nuclei. Although there is no consensus on the mass of its central engine, several estimates suggest it to be


Narrowband HST images of M87: Evidence for a disk of ionized gas around a massive black hole
We present Hubble Space Telescope Wide Field/Planetary Camera-2 (HST WFPC2) narrowband H-alpha + (N II) images of M87 which show a small disk of ionized gas with apparent spiral structure surrounding
HST FOS spectroscopy of M87: Evidence for a disk of ionized gas around a massive black hole
Using the Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST) to observe the central region of M87, we have obtained spectra covering approximately 4600-6800 A at a spectral
New measurements of stellar kinematics in the core of M87
New, high S/N spectra of the core of M87 are presented which confirm Dressler's (1980) claim that the velocity dispersion does not continue to rise within r = 1 arcsec, but levels off at sigma about
Evidence for a supermassive object in the nucleus of the galaxy M87 from SIT and CCD area photometry.
Two-dimensional SIT and CCD detectors have been used to measure the surface brightness of the peculiar elliptical radio galaxy M87. Measurements were made in three broad-band colors (B, V, and R) to
A massive black hole at the centre of the quiescent galaxy M32
Massive black holes are thought to reside at the centres of many galaxies1,2, where they power quasars and active galactic nuclei. But most galaxies are quiescent, indicating that any central massive
Anisotropic velocity distributions in M87 - Is a supermassive black hole necessary
A collisionless distribution of stars with an anisotropic velocity distribution is considered as a model for the cores of spherical galaxies. The first moment of the corresponding Boltzmann equation
A large nuclear accretion disk in the active galaxy NGC4261
THE powerful emissions from the nuclei of active galaxies and quasars are thought to arise from the accretion of matter onto a massive black hole. Angular momentum will prevent matter from falling
Hubble Space Telescope photometry of the central regions of Virgo cluster elliptical galaxies. 3: Brightness profiles
We have used the Planetary Camera on the Hubble Space Telescope (HST) to study the morphology and surface brightness parameters of a luminosity-limited sample of fourteen elliptical galaxies in the
Wobbling Accretion Disks, Jets, and Point-symmetric Nebulae
We present numerical calculations of the evolution of an accretion disk that is irradiated by a central source. The parameters chosen represent those of the central star of a planetary nebula. We
Unified models for active galactic nuclei and quasars
Because the critical central regions of Active Galactic Nuclei (AGN) and quasars are strongly nonspherical but spatially unresolved, orientation effects have been the source of much confusion. In
