A Multiband Approach to AGN: Radioscopy & Radio Astronomy

M. Kadler, E. Ros, J. Kerp +3

Only in the radio-loud population of active galactic nuclei (AGN) does the production, collimation, and acceleration of powerful relativistic jets take place. We introduce here a c…

Synchrotron Self-Compton Model for Rapid Nonthermal Flares in Blazars with Frequency-Dependent Time Lags

Andrei Sokolov, Alan P. Marscher, Ian M. McHardy

We model rapid variability of multifrequency emission from blazars occurring across the electromagnetic spectrum (from radio to gamma-rays). Lower energy emission is produced by th…

The Highly Relativistic Kiloparsec-Scale Jet of the Gamma-Ray Quasar 0827+243

Svetlana Jorstad, Alan Marscher

We present Chandra X-ray (0.2-8 keV) and Very Large Array radio (15 and 5 GHz) images of the -ray bright, superluminal quasar 0827+243. The X-ray jet bends sharply--by ~90 deg.,…
