X-rays from Clusters of Galaxies

  title={X-rays from Clusters of Galaxies},
  author={Steven W. Allen},
The X-ray emission from clusters of galaxies enables them to be used as good cosmological probes and as an example for massive galaxy formation. The gas mass fraction in clusters should be a universal standard which by means of Chandra observations enables Ωm to be determined to better than 15 per cent accuracy. Future observations of its apparent variation… CONTINUE READING
