Scientific paper

We present preliminary results on the dynamics of the Abell clusters A160, A690, and A2462, and the poor clusters 1919+479, and 1313+473, each containing a wide-angle tailed (WAT) radio source. These powerful radio sources are associated with the clusters' dominant, elliptical galaxies and possess two tails extending hundreds of kiloparsecs. Multifiber spectroscopy is being performed to gather enough velocities to run normality and substructure tests. We have previously showed for A2634, that the tails of 3C465 may be bent by the large scale motions in the intracluster gas following a cluster-subcluster merger. We wish to investigate the hypothesis that the powering and shaping of WATs in other clusters may result from the disturbance of a cluster-subcluster merger. This work was supported by NSF grant AST-9012353 and NASA grant NAGW-5152.
