Study of X-ray Reflection Features in a Sample of Sy 1s Observed by Bepposax
نویسنده
چکیده
The ionized disc reflection model of Ross & Fabian is applied to a sample of five Seyfert 1 galaxies observed by BeppoSAX. Good fits were obtained for all the objects in the sample. NGC 4051 and Mkn 335 (usually classified as NLSy 1s) show evidence of a highly ionized accretion disc (ξ ∼ 350 erg cm s and ξ ∼ 800 erg cm s). While NGC 3783 seems to be a “pure Sy 1” characterized by a highly ionized accretion disc (ξ ∼ 500 erg cm s). All the sources are consistent with having a face-on disc. The accurate determination of the continuum emission allows us to investigate the spectral variability in the case of Mkn 509.

Seyfert Galaxies: Nuclear Radio Structure and Unification
We have observed a sample of Seyfert (Sy) galaxies with the global Very Long Baseline Interferometry (VLBI) to test the predictions of the unification scheme for the Sy galaxies which hypothesises that Sys of Type 1 and of Type 2 constitute a single population of objects. If Sy 1 and Sy 2 galaxies differ only in the orientation of the axisymmmetric active nucleus with respect to the observer, t...
متن کاملBeppoSAX observations of Seyfert 1 s in the Piccinotti sample I : poorly studied sources
In this work we present the first of two papers devoted to the study of the X-ray spectral characteristics of Seyfert 1 galaxies in the Piccinotti sample. In particular we analyse here the BeppoSAX broad band (0.1-100 keV) data of 4 objects which, despite their X-ray brightness, have been historically poorly studied due to their late identification with an AGN We have assumed for all the source...
متن کاملThe broad band spectral properties of galactic X–ray binary pulsars
BeppoSAX observed several galactic binary X–ray pulsars during the Science Verification Phase and in the first year of the regular program. The complex emission spectra of these sources are an ideal target for the BeppoSAX instrumentation, that can measure the emission spectra in an unprecedented broad energy band. Using this capability of BeppoSAX a detailed observational work can be done on t...
متن کاملBepposax Observations of Bright Radio Galax- Ies
BeppoSAX observations of Broad Line Radio Galaxies (BLRGs) have shown that they have a considerable variety of spectral properties and important differences with respect to their radio-quiet counter-part Seyfert 1s. In radio galaxies the soft photons are often absorbed by cold material. In contrast, in Seyfert 1s the soft photons are generally absorbed by warm gas. The iron lines, always detect...
متن کاملEffects of the stellar wind on X-ray spectra of Cygnus X-3
We study X-ray spectra of Cyg X-3 from BeppoSAX, taking into account absorption and emission in the strong stellar wind of its companion. We find the intrinsic X-ray spectra are well modelled by disc blackbody emission, its upscattering by hot electrons with a hybrid distribution, and by Compton reflection. These spectra are strongly modified by absorption and reprocessing in the stellar wind, ...
