Optical Proper Motion Measurements of the M87 Jet: New Results from the Hubble Space Telescope
Eileen T. Meyer, W. B. Sparks, J. A. Biretta +5
We report new results from an HST archival program to study proper motions in the optical jet of the nearby radio galaxy M87. Using over 13 years of archival imaging, we reach accu…
A Multiwavelength Spectral and Polarimetric Study of the Jet of 3C 264
Eric S. Perlman, C. Alex Padgett, Markos Georganopoulos +12
We present a comprehensive multiband spectral and polarimetric study of the jet of 3C 264 (NGC 3862). Included in this study are three HST optical and ultraviolet polarimetry data…
Variability Timescales in the M87 Jet: Signatures of E-Squared Losses, Discovery of a Quasi-period in HST-1, and the Site of TeV Flaring
D. E. Harris, C. C. Cheung, Lukasz Stawarz +2
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 lightcurves of HS…
The Outburst of HST-1 in the M87 Jet
D. E. Harris, C. C. Cheung, J. A. Biretta +4
The X-ray intensity of knot HST-1, 0.85" from the nucleus of the radio galaxy M87, has increased by more than a factor of 50 during the last 5 years. The optical increase is simila…
Flaring X-ray Emission from HST-1, a Knot in the M87 Jet
D. E. Harris, J. A. Biretta, W. Junor +3
We present Chandra X-ray monitoring of the M87 jet in 2002, which shows that the intensity of HST-1, an optical knot 0.8" from the core, increased by a factor of two in 116 days an…
A Comparison of the Extra Nuclear X-ray and Radio Features in M87
D. E. Harris, F. Owen, J. A. Biretta +1
ROSAT High Resolution Imager (HRI) data from eight observations have been co-added to obtain an effective exposure of 230 ksec. We have identified a number of features and regions…
