Query: PKS2250-41 and the role of jet-cloud interactions in powerful radio
  galaxies   We have studied the effects of the interaction between the radio jet and the
ambient gas in the powerful radio galaxy PKS2250-41 (z=0.31). Our results show
that the gas has been accelerated, compressed, heated and collisionally ionized
by the shock. This study helps us to understand the processes which determine
the observed properties of many high redshift radio galaxies.
