Merger of massive galaxy cluster CL0238.3+2005 at z~0.4: just after pericenter passage?

N. Lyskova, E. Churazov, I. Khabibullin +13

Massive clusters of galaxies are very rare in the observable Universe. Even rarer are mergers of such clusters observed close to pericenter passage. Here, we report on one such cas…
