It is the galaxie M86 that come near the Virgo galaxies Cluster. notice that the cause of hot gaz inter galaxies cluster is probably from

then theirs pressures also and this cause a few slowing of the colapse of the galaxies.
    Also the collapse of galaxies do more super nova that send out énergy and particles.
