We present optical long-slit spectroscopy of the nucleus of the nearby radio galaxy M84 (NGC 4374 = 3C 272.1) obtained with the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope. Our spectra reveal that the nuclear gas disk seen in the Wide Field Planetary Camera 2 imaging by Bower et al. is rotating rapidly. The velocity curve has an S-shape with a peak amplitude of 400 km s−1 at 01 = 8 pc from the nucleus. To model the observed gas kinematics, we construct a thin… 
Evidence for a Supermassive Black Hole in the S0 Galaxy NGC 3245
The S0 galaxy NGC 3245 contains a circumnuclear disk of ionized gas and dust with a radius of 1A (110 pc), making it an ideal target for dynamical studies with the Hubble Space Telescope (HST ). We
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
Nuclear Disks of Gas and Dust in Early-Type Galaxies and the Hunt for Massive Black Holes: Hubble Space Telescope Observations of NGC 6251
We discuss Hubble Space Telescope (HST) optical images and spectra of NGC 6251, a giant E2 galaxy and powerful radio source at a distance of 106 Mpc (for H0=70 km s-1 Mpc-1). The galaxy is known to

The Ionization Source in the Nucleus of M84
We have obtained new Hubble Space Telescope observations of M84, a nearby massive elliptical galaxy whose nucleus contains a ≈1.5 × 109 M☉ dark compact object, which presumably is a supermassive
The Black Hole in IC 1459 from Hubble Space Telescope Observations of the Ionized Gas Disk
The peculiar elliptical galaxy IC 1459 (MV = -21.19, D = 16.5 h-1 Mpc) has a fast counterrotating stellar core, stellar shells and ripples, a blue nuclear point source, and strong radio core
Evidence for a Massive Black Hole in the S0 Galaxy NGC 4342
We present axisymmetric dynamical models of the edge-on S0 galaxy NGC 4342. This small low-luminosity galaxy harbors, in addition to its outer disk, a bright nuclear stellar disk. A combination of
