Abstract (from CDS):

Three high redshift radio galaxies, 1345+245 (4C24.28, z=2.889), 1809+407 (4C40.36, z=2.267) and 2349+289 (4C28.58, z=2.905) were observed with VLBI at 327MHz giving an angular resolution of ≃40-100mas and yielding images with the off-source noise level of 3σ≃3.5mJy/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.
