Scientific paper

The two interpretations suggested for the Chandra-detected X-ray emission of the large scale jets of powerful quasars are external Compton (EC) scattering off the cosmic microwave background (CMB) photons (EC/CMB) and synchrotron emission from a population of electrons separate from those producing the radio - IR emission. Here we present a way to discriminate between the two models based on a fundamental difference they have: the production of synchrotron X-rays requires multi - TeV electrons, while the EC/CMB model requires a cutoff in the electron energy distribution (EED) below TeV energies. This has significant implications for the γ-ray emission predicted by these two models, that can be tested through GeV and TeV observations of the nearby bright quasar 3C 273.
