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…
Multiwavelength Observations of the Powerful Gamma-ray Quasar PKS 1510-089: Clues on the Jet Composition
J. Kataoka, G. Madejski, M. Sikora +16
We present the results from a multiwavelength campaign of the powerful Gamma-ray quasar PKS 1510-089. This campaign commenced with a deep Suzaku observation lasting three days for…
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…
The Case of the 300 kpc Long X-ray Jet in PKS 1127-145 at z=1.18
Aneta Siemiginowska, D. E. Harris, Thomas L. Aldcroft +4
The complex X-ray morphology of the 300 kpc long X-ray jet in PKS1127-145 (z=1.18 quasar) is clearly discerned in a ~100 ksec Chandra observation. The jet X-ray surface brightness…
Radio Loudness of AGNs: Host Galaxy Morphology and the Spin Paradigm
L. Stawarz, M. Sikora, J. -P. Lasota
We investigate how the total radio luminosity of AGN-powered radio sources depends on their accretion luminosity and the central black hole mass. We find that AGNs form two distinc…
Intermittent jet activity in the radio galaxy 4C29.30?
M. Jamrozy, C. Konar, D. J. Saikia +3
We present radio observations at frequencies ranging from 240 to 8460 MHz of the radio galaxy 4C29.30 (J0840+2949) using the Giant Metrewave Radio Telescope (GMRT), the Very Large…
