Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
X-RAY STUDY OF PRE-MERGING CLUSTER A3530 AND A3532
ABSTRACT
We propose to observe a pre-merging cluster pair A3530 and A3532. The projected distance between A3530 and A3532 is 2.5 Mpc, and their line-of-sight velosity separation is ~330 km/s. We thus interpret the cluster pair as currently being in a pre-merging phase. In order to obtain meaningful statistics, we propose to observe the pair regoin for 100 ksec total.
