Main Conclusions

  1. 1)

    The probability distributions of the basic kinematic parameters of radio galaxies can be described by simple analytic expressions (the gamma distribution (7) with γ=2 and 3 and the distribution (9)), these making it possible to determine from observations the characteristics separation velocity of the components under the assumption of a fixed lifetime of the radio sources.

  2. 2)

    Application of the proposed method to analysis of the sample of radio galaxies in [2] showed that the velocity of the hot spots in the “heads” of powerful radio galaxies has characteristic magnitude v≲9000 km/sec, the asymmetry parameters R and Q being due to differences in the initial conditions of the ejections and differences in the parameters of the surrounding intergalactic medium.

  3. 3)

    An important parameter of a sample of radio sources is the maximal observed linear size1 *max , since the characteristic velocity v of the motion of the components and the characteristic lifetime T of the sources depend on it.
