ABSTRACT

The 1745+624 and PKS 1127−14 quasar jets are considered. The X-ray emission of the near-central source knots is produced by the inverse Compton scattering of quasar radiation, while the inverse Compton scattering on the cosmic microwave background occurs at distant knots. The competition of these mechanisms has allowed to estimate the angles between the jets and the line of sight. The ratio of X-ray to radio flux densities of distant knots is shown to conform to the theoretical dependence on the redshift.
