    • Jets and multi-phase turbulence . 

      Krause, M.~G.~H. (Memorie della Societa Astronomica Italiana, 2008-06-06)
      Jets are observed to stir up multiphase turbulence in the interstellar medium as well as far beyond the host galaxy. Here we present detailed simulations of this process. We evolve the hydrodynamics equations with optically ...

    • The jets in 3C 296
