Abell 754 [SEP] constellation
Abell 754
Abell 754 is a galaxy cluster in the constellation Hydra that was formed from the collision of two smaller clusters. This collision, which began about 300 million years ago, is ongoing, and the system is still disturbed. Eventually, the cluster will reach a level of equilibrium in a few billion years.

the prototype relic source 1253 + 275), Abell 2255 and Abell 2256, which contain both a relic and a halo (as do Abell 225, Abell 521, Abell 754, Abell 1300, Abell 2255 and Abell 2744). The cluster Abell 3667 contains two very luminous, almost symmetric
relics with a separation of more than 5 Mpc, as does ZwCl 2341.1+0000, Abell 2345, Abell 1240, and ZwCl 0008.8+5215. The relic with the best evidence for shock acceleration found to date is located
