We report preliminary results from Magellan optical imaging of FR II jet sources. These are the first objects observed as part of our campaign to study a complete sample of radio-selected quasar jets in optical and X-rays. Different emission mechanisms may dominate at different locations within a jet or from jet to jet. Measuring optical fluxes and flux upper limits in spatially-resolved structures provides critical constraints for the emission models. We construct SEDs for regions within each jet using these optical data, combined with radio (ATCA and VLA) and X-ray (Chandra) imaging. We use the SEDs to discriminate between synchrotron and various inverse Compton emission scenarios for the high-energy flux, and to constrain the physical conditions present at points along the jets.
This work has been supported in part by Chandra GO grant G02-3151A from SAO and NASA contract NAS8-39073 to the Chandra X-ray Center.
