We studied galaxy clusters Abell 119, Abell 754, and Abell 1750, using data from the ASCA and ROSAT satellites. These three clusters were chosen from a larger sample based on large temperature gradients in their temperature profiles and non-uniform distributions in their X-Ray intensities. Abell 119 has a cool region in the northeast, with temperatures decreasing toward the southwest. Abell 754 shows evidence for a shock in its temperature maps. Abell 1750 also shows evidence for a shock, located between two of the three components of the cluster. All of these exhibited signs of merger activity within their central region, as well as evidence for possible large scale ( ~ 1Mpc) filamentary structure. These filaments may represent the preferred direction of accretion into these clusters.
