Binary merging clusters in the Hercules galaxy supercluster.
KREMPEC-KRYGIER J., KRYGIER B. and KRYWULT J.
Abstract (from CDS):
The velocity fields of galaxy clusters in four binary systems in the Hercules supercluster, (A2197-A2199), (A2147-A2151), (A2147/51-A2152) and (A2052-A2040), are investigated. The radial and circular orbit models, as well as merger after off-center collisions are discussed. We find that the (A2197-A2199), (A2147-A2151) and (A2147/51-A2152) systems are gravitationally bound. For the (A2052-A2040) system the results are less conclusive.
