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
the speed of galaxies that come near each other, there is gaz around galaxies and the collapse of galaxies grew the gaz température,
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.
