    Absorption at the Dust Sublimation Radius and the Dichotomy Between X-ray and Optical Classification in the Seyfert Galaxy H0557-385
    In this work, the analysis of multi-epoch (1995-2010) X-ray observations of the Seyfert 1 galaxy H0557-385 is presented. The wealth of data presented in this...
