BeppoSAX observations of Mrk 841 and Mrk 335

Abstract

We present and discuss BeppoSAX observations of Mrk 841 and Mrk 335, two Seyfert 1 galaxies in which previous observations have established the presence of soft excesses. We conrm the soft excess in both sources, even if for Mrk 841 a warm absorber provides a t almost as good as the one with a true excess. As far as the hard X-ray continuum is concerned, a Comptonization model provides a t as good as a power law and a physically sound solution for Mrk 841. For Mrk 335, the Comptonization model gives a result which is somewhat better on statistical ground, but rather problematic on physical ground. The most interesting results regard the reprocessing components. For Mrk 841 we nd a very large reflection continuum but an almost normal iron line equivalent width even if, within the errors, a solution in which both components are a factor2 larger than expected for an accretion disc is still marginally acceptable. If this is the case, an anisotropy of the primary emission seems the best explanation. On the contrary, in Mrk 335 we nd a very large iron line EW but a reflection component not accordingly large. In this case, the best solution seems to be in terms of reflection from an ionized disc.
