Seyfert Galaxies and BeppoSAX
In this review, rather than present and discuss in detail the first results obtained by BeppoSAX (see Boella et al. 1997 for an overall description of the mission) on Seyfert galaxies (these results are presented in detail elsewhere in this volume, see in particular the contributions by Perola, Comastri and Salvati), I will discuss current ideas on the X–ray emission of both type 1 and 2 object...
متن کاملBeppoSAX average spectra of Seyfert galaxies
We have studied the average 3-200 keV spectra of Seyfert galaxies of type 1 and 2, using data obtained with BeppoSAX. The average Seyfert 1 spectrum is well-fitted by a power law continuum with photon spectral index Γ ∼ 1.9, a Compton reflection component R∼0.6-1 (depending on the inclination angle between the line of sight and the reflecting material) and a high-energy cutoff at around 200 keV...
متن کاملThe BeppoSAX view of bright Compton-thin Seyfert 2 galaxies
We present the analysis of 31 observations (17 of which are published here for the first time) of 20 bright Compton thin Seyfert 2s, in the 0.1-200 keV band, performed with the BeppoSAX satellite. The sample consists of all Seyfert 2s in the BeppoSAX public archive, with a 2-10 keV flux higher than 5×10−12 erg cm−2s−1. The good statistics available and the broad energy band permit a detailed st...
متن کاملCompton reflection and iron fluorescence in BeppoSAX observations of Seyfert type 1 galaxies
A sample of nine bright Seyfert 1 and NELG type galaxies, observed with BeppoSAX, is analyzed to assess on a truly broad band basis (0.1–200 keV) the issue of the spectral contributions of Compton reflection and iron line fluorescence from circumnuclear gas. The empirical description adopted for the direct continuum is the commonly used power law with an exponential cut–off. The most direct tes...
متن کاملX-ray reprocessing in Seyfert Galaxies: simultaneous XMM-Newton/BeppoSAX observations
We selected a sample of eight bright unobscured (at least at the iron line energy) Seyfert Galaxies observed simultaneously by XMM-Newton and BeppoSAX, taking advantage of the complementary characteristics of the two missions. The main results of our analysis can be summarized as follows: narrow neutral iron lines are confirmed to be an ubiquitous component in Seyfert spectra; none of the analy...
