[53.01] Rotational flows within superclusters? A comparison of redshift-space artifacts in the Local and Southern Superclusters

E.A. Praton, M.A. Berger (Franklin & Marshall College)

We continue a study of possible non-radial flows within the two nearest superclusters. Both the Ursa Major region in the Local Supercluster and the Dorado region in the Southern Supercluster show structures in redshift-space which look like the artifact expected for flow with non-zero curl about a small central cluster: a small finger of god, bisected by a “bow-tie.”

Previously, we used the Tully-Fisher relation to confirm our identification of a finger in the Ursa Major region (Praton, Rothrock, & Schneider 2000). We now extend the investigation to include a comparison with the Dorado finger. We also use the T-F relation to investigate the apparent bow-tie artifacts in both regions.
