## [38.07] A Search for X-Ray Filaments in Galaxy Clusters

M. Novicki (UofM \& SAO), C. Jones, R. Hank Donnelly (SAO)

We studied galaxy clusters Abell 119, Abell 754, and Abell 1750, using data from the {\em ASCA} and {\em 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.
