Abstract. Three high redshift radio galaxies, 1345+245 (4C 24.28, z = 2.889), 1809+407 (4C 40.36, z = 2.267) and 2349+289 (4C 28.58, z = 2.905) were observed with VLBI at 327 MHz giving an angular resolution of 40-100 mas and yielding images with the off-source noise level of 3σ 3.5 mJy/beam. On the centiarcsecond scale, the three sources are each characterized by two components with asymmetry both in flux density and in size. The compact components in the VLBI maps correspond to the hot spots in the VLA maps. No radio cores have been detected. The physical parameters for the components derived are consistent with a model in which shocks accelerate electrons in the hotspots.

Abstract. This paper presents our investigations of statistical behavior of the small-scale jet orientations and the intrinsic polarization position angles. We found that the distribution of the milliarcsecond-scale jet orientations and intrinsic polarization position angles of extragalatic radio sources appears anisotropic with high significance levels in most cases.
