The Highest Redshift Relativistic Jets
C. C. Cheung, L. Stawarz, A. Siemiginowska +5
We describe our efforts to understand large-scale (10's-100's kpc) relativistic jet systems through observations of the highest-redshift quasars. Results from a VLA survey search f…
Electron Energy Distributions at Relativistic Shock Sites: Observational Constraints from the Cygnus A Hotspots
C. C. Cheung, L. Stawarz, D. E. Harris +1
We report new detections of the hotspots in Cygnus A at 4.5 and 8.0 microns with the Spitzer Space Telescope. Together with detailed published radio observations and synchrotron se…
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…
