| description | The present paper is concerned with four quasars which, according to previous work, have a noncollinear radio structure. Hintzen and Scott (1978) have proposed that quasars with noncollinear radio structure are members of clusters of galaxies. If this were always true, dogleg quasars could be used to locate very distant clusters of galaxies in connection with the study of important questions of cosmological evolution. However, Hintzen and Scott assumed that the noncollinearity of the considered quasar radio sources is caused by the presence of a dense ICM (intracluster medium). If that were true, the detailed radio morphology of these sources should be very similar to FR class 1 radio galaxies. For this reason, maps were obtained of the four quasers with the aid of the Very Large Array (VLA) of the NRAO. The results confirm that the radio structure in all four cases is noncollinear. However, the observed structures do not resemble FR class 1 radio galaxies at all. The significance of these results is discussed. 67 references. |
