Taking advantage of the high sensitivity of ESA's XMM-Newton and the sharp vision of NASA's Chandra X-Ray space observatories, astronomers have studied the behaviour of massive fossil galaxy clusters, trying to find out how they find the time to form. Many galaxies reside in galaxy groups, where they experience close encounters with their neighbours and interact gravitationally with the dark matter - mass which permeates the whole intergalactic space but is not directly visible because it...

RAS -- Researchers at the University of Birmingham have used the new generation of X-ray space observatories to study fossil galaxies - ancient galaxy groups in which all of the large galaxies have gradually merged to form one central giant galaxy. The astronomers discovered a remarkable concentration of dark and normal matter in the cores of these isolated star systems, compared with the mass distribution in normal galaxy groups. Many galaxies, including our Milky Way, reside in groups....
