HUBBLE SPACE TELESCOPE Observations of Superluminal Motion in the M87 Jet
We present observations of the M87 jet made with the Faint Object Camera on board the Hubble Space Telescope at five epochs between 1994 and 1998. These observations reveal 10 superluminal featuresExpand
Formation of the radio jet in M87 at 100 Schwarzschild radii from the central black hole
Massive galaxies often are the source of well collimated jets of material that flow outwards for tens to hundreds of kiloparsecs from the regions surrounding the presumed black holes at theirExpand
Hubble Space Telescope Observations* of Globular Clusters in M87 and an Estimate of H0
Hubble Space Telescope observations of over 1000 globular clusters in the central region of M87 have been made using the Wide Field and Planetary Camera 2. The limiting magnitude in V is 26 mag, moreExpand
VARIABILITY TIMESCALES IN THE M87 JET: SIGNATURES OF E 2 LOSSES, DISCOVERY OF A QUASI PERIOD IN HST-1, AND THE SITE OF TeV FLARING
We investigate the variability timescales in the jet of M87 with two goals. The first is to use the rise times and decay times in the radio, ultraviolet, and X-ray light curves of HST-1 to constrainExpand
Deep 10 Micron Imaging of M87
We analyze a 10.8 ?m image of M87, obtained with the Gemini 8 m telescope + OSCIR. The image has better than 05 resolution and represents 7 hr of observing time, making it the deepest high-resolutionExpand
HST Snapshot Survey of 3CR Radio Source Counterparts. I. Intermediate Redshifts
We have obtained images of 267 3CR radio galaxies and quasars by conducting a snapshot survey with HST's WFPC2 through a broadband red (F702W) filter. This is the first in a series of papersExpand
Subluminal Motion and Limb Brightening in the Nuclear Jet of M87
A high dynamic range VLBI map of the 1.6 GHz emission from the nucleus of M87 is presented. The nuclear jet of M87 has a very complex brightness distribution that appears to be stronglyExpand
Wide Field and Planetary Camera 2 Instrument Handbook
A motion picture film projector includes a sound head for playing back or for recording a sound track on the film. Absolute synchronism between the picture and sound is assured by the use of a singleExpand
