    • Catastrophic cooling in solar coronal loops - thermal instability as a road to complex evolution 

      Müller, Daniel (Univ. Freiburg (Breisgau), 2005)
      Satellite observations with high spatial and temporal resolution have revealed the highly dynamic nature of the solar corona and enabled us to study physical processes in the outer atmosphere of our mother star in great ...
    • Constraining the UV background with the proximity effect 

      Dall'Aglio, Aldo (Univ. Potsdam, 2009)
      After the epoch of reionisation the intergalactic medium (IGM) is kept at a high photoionisation level by the cosmic UV background radiation field. Primarily composed of the integrated contribution of quasars and young ...
    • The metagalactic UV background at z < 3 

      Fechner, Cora (Univ. Hamburg, 2005)
      The high ionization state of the intergalactic medium (IGM) is maintained by the metagalactic UV background radiation. This ionizing radiation field is supposed to be the integrated radiation of quasars and young star-forming ...
