Signatures of interstellar-intracluster medium interactions: spiral galaxy rotation curves in Abell 2029.


Abstract (from CDS):

We investigate the rich cluster Abell 2029 (z∼0.08) using optical imaging and long-slit spectral observations of 52 disk galaxies distributed throughout the cluster field. No strong emission-line galaxies are present within ∼400 kpc of the cluster center, a region largely dominated by the similarly shaped X-ray and low surface brightness optical envelopes centered on the giant cD galaxy. However, two-thirds of the galaxies observed outside the cluster core exhibit line emission. Hα rotation curves 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 Tully-Fisher zero point of Abell 2029 matches that of clusters at lower redshifts, although we do observe a relatively larger scatter around the Tully-Fisher relation. We do not observe any systematic variation in the data with projected distance to the cluster center. We see no environmental dependence of Tully-Fisher residuals, R-I color, Hα equivalent width, or the shape and extent of the rotation curves.
