Title: Panchromatic Views of Large-Scale Quasar Jets 
Authors: C.C. Cheung 
Topic: 1 
Session: oral 
Abstract: Chandra observations have established that X-ray 
emission is a common feature of large-scale jets in AGN.  
In the X-ray jets detected on 100\'s kpc-scales in powerful 
quasars, canonical synchrotron models do not adequately 
fit the radio-to-X-ray spectra. In such cases, a widely applied 
model is inverse Compton (IC) scattering off CMB 
photons by relativistic electrons in a highly relativistic jet 
(Lorentz factors ~10). \"Non-standard\" synchrotron models 
have also been proposed but no concensus has been reached.  
I will give an overview of this subject, highlighting results
 from recent observations with Chandra and Spitzer.  Recent results 
from studies of the highest-redshift (z~4) radio/X-ray quasar jets will 
be presented. The IC/CMB and synchrotron models have strongly 
diverging predictions for the X-ray emission at such high-redshifts 
and this is discussed.
