New insights into jet physics from Chandra and HST observations
Abstract
We report on new joint Chandra-HST observations of a sample of large-scale jets hosted by powerful radio-loud QSOs. The favoured emission mechanism of the high-energy radiation is the Inverse Compton scattering of the CMB photons, although some criticisms have been recently raised. Deeper pointings of two particularly interesting jets show a remarkable behaviour of the overall radio-optical-X-ray continuum, which is convex in the innermost knots and concave in the outer regions. This evidence suggests a "transition" of the emission mechanism (from synchrotron to IC/CMB) responsible for the emission of X-rays along the jet. We discuss the implications for the physics of the jet.
