We propose deep ACIS observations of two nearby clusters, A514 and A2147, both of whose X-ray emission show unusually complex structures, that are likely related to ongoing mergers. Since both are nearby, Chandra's angular resolution will allow these structures to be studied with unprecedented detail. In particular for A2147, we will determine if the sharp ``edge'' in its surface brightness is due to a merger or to the motion of a central gas cloud in the cluster ICM. We will map the temperature, as well as the density, across the edge. The cluster A514 has head-tail radio sources, for which we plan to investigate if a cluster-subcluster merger, rather than the galaxies own motion through the intracluster medium, is responsible for bending the tails.
