    • X-RAY TRANSMISSION AND REFLECTION THROUGH A COMPTON-THICK MEDIUM VIA MONTE-CARLO SIMULATIONS 

      Autor: Eikmann , Wiebke; Wilms , Jörn; Smith K., Randall; Lee C., Julia
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The spectral shape of an X-ray source strongly depends on the amount and distribution of the surrounding material. The spectrum of a primary source which is located in an optically thin medium with respect to Compton ...

    • X-RAY VARIABILITY STUDY OF POLAR SCATTERED SEYFERT1 GALAXIES 

      Autor: Beuchert, Tobias; Wilms, Jörn; Kadler, Matthias; Longinotti, Anna Lia; Guainazzi, Matteo; Miniutti, Giovanni; de la Calle, Ignacio
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      We study 12 Seyfert 1 galaxies with a high level of optical polarization. Optical light emerging from the innermost regions is predominantly scattered in a polar region above the central engine directly in our line of ...
