We present results from Chandra X-ray imaging and spectroscopy of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like extended structure. Twelve of twenty quasar jets are detected in 5 ks ACIS-S exposures from our initial survey and two of five show jets in the survey continuation (so far). The quasars without X-ray jets are not significantly different from those with detected jets except that the extended radio emission is generally somewhat fainter. New radio maps are combined with the X-ray images in order to elucidate the relation between radio and X-ray emission in spatially resolved structures. We find a variety of morphologies. The FR II X-ray jets can all be interpreted as inverse Compton scattering of cosmic microwave background photons by electrons in large-scale relativistic jets.
In the jet of PKS 1421-490, we have found a unique optically-dominated knot that is ˜200-300 times brighter than the core in the optical band and 3.5 times brighter in X-rays. Its optical spectrum is featureless, ruling out most possible sources of contamination; a deeper upcoming observation will both improve the S/N of the jet spectrum and allow us to measure the redshift of the core. (From photometric colors, z>2.5.)
