Deceleration from Entrainment in the jet of the quasar 1136-135?
F. Tavecchio, L. Maraschi, R. M. Sambruna +4
Modeling the multiwavelength emission of successive regions in the jet of the quasar PKS 1136-135 we find indication that the jet suffers deceleration near its end on a (deprojecte…
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…
Deep Chandra and multicolor HST follow-up of the jets in two powerful radio quasars
R. Sambruna, M. Gliozzi, D. Donato +5
We present deep (70-80 ks) Chandra and multicolor HST ACS images of two jets hosted by the powerful quasars 1136-135 and 1150+497, together with new radio observations. The sources…
X-ray Cluster Associated with the z=1.063 CSS Quasar 3C 186: The Jet is NOT Frustrated
Aneta Siemiginowska, C. C. Cheung, Stephanie LaMassa +6
We report the Chandra discovery of an X-ray cluster at redshift z = 1.063 associated with the Compact Steep Spectrum radio loud quasar 3C 186 (Q0740+380). Diffuse X-ray emission is…
Discovery of Optical Emission in the Hotspots of Three 3CR Quasars: High-Energy Particle Acceleration in Powerful Radio Hotspots
C. C. Cheung, J. F. C. Wardle, T. Chen
Archival Hubble Space Telescope WFPC2 images were used to search for optical emission associated with the radio jets of a number of luminous quasars. From this search, we report ne…
