Signatures of interstellar-intracluster medium interactions: Spiral galaxyrotation curves in abell 2029

We investigate the rich cluster Abell 2029 (z similar to 0.08) using optica l imaging and long-slit spectral observations of 52 disk galaxies distribut ed throughout the cluster field. No strong emission-line galaxies are prese nt within similar to 400 kpc of the cluster center, a region largely domina ted by the similarly shaped X-ray and low surface brightness optical envelo pes centered on the giant cD galaxy. However, two-thirds of the galaxies ob served outside the cluster core exhibit line emission. H alpha rotation cur ves of 14 cluster members are used in conjunction with a deep I-band image to study the environmental dependence of the Tully-Fisher relation. The Tul ly-Fisher zero point of Abell 2029 matches that of clusters at lower redshi fts, although we do observe a relatively larger scatter around the Tully-Fi sher relation. We do not observe any systematic variation in the data with projected distance to the cluster center. We see no environmental dependenc e of Tully-Fisher residuals, R-I color, Ha equivalent width, or the shape a nd extent of the rotation curves.
