Inverse compton scattering of power-low photon spectrum for astrophysical application

summary form only given. Inverse Compton scattering is the interaction process between photons and ultrarelativistic electrons as a result of this process, the frequency of scattered photons violently increases. This mechanism plays important part in origin of X-ray and gamma-ray emission in astrophysical objects, such as jets of quasars and active galaxies, supernova remnants, pulsars. Generally, in this objects the frequency and energy distributions have a low-power nature due to the acceleration processes of cosmic rays. Usually, the consideration of inverse Compton effect is constrained by assumption that the scattering emission is isotropic [1]. For example, such situation takes place at the scattering on the cosmic microwave background. In present work we analyze the inverse Compton scattering of anisotropic low-power radio emission of quasar on relativistic jet´s electrons by the example of the nearest quasar 3C 273. The flux density of quasar emission is F(ω)∞ω^-α . The relativistic electrons in the nearest to the quasar knot (the region of increased surface brightness in which acceleration processes occur) of kiloparsec jet have low-power energy spectrum f(Γ)∞Γ^-γ, it follows from data of his optical and radio synchrotron emission. In present task the angle of the jet with line of sight, it is also the angle between initial and scattered photon impulses, is known θ ≈ 30° [2].
