ACCRETION ONTO THE SUPERMASSIVE BLACK HOLE IN M87
Chandra X-ray observations of the giant elliptical galaxy M87 resolve the thermal state of the hot interstellar medium into the accretion (Bondi) radius of its central 3 × 109 M☉ black hole. WeExpand

Multiwavelength tests of the dusty torus model for Seyfert galaxies
We present a compilation of emission properties for a sample of 116 Seyfert galaxies based on both previously unpublished data and measurements available in the literature. These measurements includeExpand

Radio sources in low-luminosity active galactic nuclei IV. Radio luminosity function, importance of jet power, and radio properties of the complete Palomar sample
We present the completed results of a high resolution radio imaging survey of all (∼200) low-luminosity active galactic nuclei (LLAGNs) and AGNs in the Palomar Spectroscopic Sample of all (∼488)Expand

Radio Structures of Seyfert Galaxies. VIII. A Distance- and Magnitude-Limited Sample of Early-Type Galaxies
The VLA has been used at 3.6 and 20 cm to image a sample of about 50 early-type Seyfert galaxies with recessional velocities less than 7000 km s-1 and total visual magnitude less than 14.5.Expand

Size and structure of the narrow-line region of quasars
We have observed the narrow-line regions (NLRs) of the seven brightest radio-quiet Palomar-Green (or Bright Quasar Survey) quasars (z < 0.5) with the Wide Field Planetary Camera 2 on board the HubbleExpand

Hubble Space Telescope and VLA Observations of Seyfert 2 Galaxies: The Relationship between Radio Ejecta and the Narrow-Line Region*
We present HST/WFPC2 images, in narrowband filters containing the [O III] λ5007 and Hα + [N II] emission lines and their adjacent continua, of a sample of seven Seyfert 2 galaxies selected becauseExpand

Radio structures of Seyfert galaxies. VII. Extension of a distance-limited sample
The VLA has been used at 6 and 20 cm to observe 27 Seyfert galaxies with recessional velocities less than 4600 km/s that had not been mapped previously. The sample shows weak trends for Seyfert 2Expand

THE MURMUR OF THE SLEEPING BLACK HOLE: DETECTION OF NUCLEAR ULTRAVIOLET VARIABILITY IN LINER GALAXIES
LINER nuclei, which are present in many nearby galactic bulges, may be the manifestation of low-rate or low-radiative-efficiency accretion onto supermassive central black holes. However, it has beenExpand

Chandra Imaging of the X-Ray Core of the Virgo Cluster
We report subarcsecond X-ray imaging spectroscopy of M87 and the core of the Virgo Cluster with the Chandra X-Ray Observatory. The X-ray morphology shows structure on arcsecond (~100 pc) to 10' (~50Expand

CHANDRA X-RAY IMAGING AND SPECTROSCOPY OF THE M87 JET AND NUCLEUS
We report X-ray imaging spectroscopy of the jet of M87 at subarcsecond resolution with the Chandra X-ray Observatory. The galaxy nucleus and all the knots seen at radio and optical wavelengths, asExpand
