MACS J0717.5+3745 [SEP] constellation
MACS J0717.5+3745
MACS J0717.5+3745 (MACS J0717 or MACS 0717 for short) is a large galaxy cluster located 5.4 billion light years away in the constellation Auriga, appearing in the MAssive Cluster Survey (MACS).
Description.
The cluster was formed by four separate galaxy clusters that have been involved in a collision. This is the first time that this phenomenon has been observed. The repeated collisions in MACSJ0717 are caused by a 13-million-light-year-long stream of galaxies, gas, and
first detection of the kinematic SZ effect in an object is observed in MACS J0717.5+3745, confirmed in 2013.
