Davies (Durham | | Abstract: | Galaxy clusters are important targets for peculiar velocity studies as a direct comparison of the various distance indicators can be made. The potential problem of an environmental effect biasing the distances to clusters of different richness is examined. The level of intrinsic cluster-to-cluster variations is also reviewed. We investigate the claim that the derived Fundamental Plane (FP) distances vary systematically with FP scatter. The cluster distances and peculiar velocities derived from Tully-Fisher, FP and Brightest Cluster Galaxies are compared and we find good agreement. | | Source: | arXiv, astro-ph/9909309 | | Services: | Forum | Review | PDF | Favorites | |
