X-RAY POINT SOURCES AND RADIO GALAXIES IN CLUSTERS OF GALAXIES [PDF]
The Astrophysical Journal, 2009 Using Chandra imaging spectroscopy and VLA L-band maps, we have identified radio galaxies at P(1.4 GHz) >= 3x10^{23} W Hz^{-1} and X-ray point sources (XPSs) at L(0.3-8 keV) >= 10^{42} ergs s^{-1} in 11 moderate redshift (0.2 99.999% level. All but one of the XPSs are hosted by luminous ellipticals which otherwise show no other evidence for AGN ...

Simulating the soft X-ray excess in clusters of galaxies [PDF]
Astronomy & Astrophysics, 2005 The detection of excess of soft X-ray or Extreme Ultraviolet (EUV) radiation, above the thermal contribution from the hot intracluster medium (ICM), has been a controversial subject ever since the initial discovery of this phenomenon. We use a large--scale hydrodynamical simulation of a concordance $Λ$CDM model, to investigate the possible thermal ...

The impact of galaxy formation on the X-ray evolution of clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We present a new model for the X-ray properties of the intracluster medium that explicitly includes heating of the gas by the energy released during the evolution of cluster galaxies. We calculate the evolution of clusters by combining the semi-analytic model of galaxy formation of Cole et al.

X-ray Morphology of Clusters of Galaxies [PDF]
Highlights of Astronomy, 1992 AbstractThe ROSAT observatory with its high spatial resolution X-ray telescope is an ideal instrument for the study of clusters of galaxies. In the first part of the mission an All Sky X-ray Survey was conducted with ROSAT. Here we present first results of observations of Virgo, Perseus and some other clusters of galaxies from the All Sky Survey. These

Primeval clusters of galaxies and the X-ray background [PDF]
Symposium - International Astronomical Union, 1978 The X-ray telescope for HEAO-B, due for launch next year, will extend our observing power in X-ray astronomy by a very large factor. For example, its sensitivity to point sources will be 103 greater than the limit of existing X-ray sky surveys. Even more intriguing will be its capability to image the all-sky X-ray background radiation on an arc minute ...
