A redshift survey between the clusters of galaxies A 548 and A 3367.

Abstract (from CDS):

In this paper we present the results of a spectroscopic survey of galaxies in an area between the two clusters of galaxies A 548 and A 3367, suspected to be a close and interacting pair. With the use of multifiber spectroscopy, we measured 180 new velocities of galaxies in the central part of A 3367 and in the external regions of A 548. The redshift histogram shows the presence of three velocity peaks, at v∼12000km/s, v∼30000km/s and v∼40000km/s, respectively. For these we estimate the density excess, the mean velocity, and the velocity dispersion. The first clump corresponds to an elongation of A 548: in particular we found a correspondence between the features of this peak and the substructures of A 548. The second peak has a velocity dispersion which is typical of clusters and the distribution of its members on the plane of the sky corresponds to the highest density peak in A 3367. We therefore suggest that the name A 3367 has to be attributed to this clump. Our general conclusion is that, differently from expected, A 548 and A 3367 do not form a close pair of merging clusters, since the two structures are at significantly different redshifts. Moreover, we found that the complex dynamical structure of A 548 has large coherence, with a projected extension in the range of 1-3h–1Mpc.
