      Ever since the discovery of the first active galactic nuclei (AGN), substantial observational and theoretical effort has been invested into understanding how massive black holes have evolved across cosmic time. Circum-nuclear ...

    • Stellar x-ray sources in the chandra cosmos survey 

      Wright, N.J.; Drake, J.J.; Civano, F. (2010-12-10)
      We present an analysis of the X-ray properties of a sample of solar- and late-type field stars identified in the Chandra Cosmic Evolution Survey (COSMOS), a deep (160 ks) and wide (∼0.9 deg ) extragalactic survey. The ...
