Superluminal Radio Features in the M87 Jet and the Site of Flaring TeV Gamma-ray Emission
C. C. Cheung, D. E. Harris, L. Stawarz
Superluminal motion is a common feature of radio jets in powerful gamma-ray emitting active galactic nuclei. Conventionally, the variable emission is assumed to originate near the…
Confronting X-ray Emission Models with the Highest-Redshift Kiloparsec-scale Jets: the z=3.89 Jet in Quasar 1745+624
C. C. Cheung, L. Stawarz, A. Siemiginowska
A newly identified kiloparsec-scale X-ray jet in the high-redshift z=3.89 quasar 1745+624 is studied with multi-frequency Very Large Array, Hubble Space Telescope, and Chandra X-ra…
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…
