BeppoSAX observations of soft X-ray Intermediate Polars
D. de Martino, G. Matt, T. Belloni +2
We present broad-band (0.1--90keV) spectral and temporal properties of the three Intermediate Polars, RE0751+144 (PQ Gem), RXJ0558.0+5353 (V405Aur) and RXJ1712.6-2414 (V2400 Oph) b…
The reprocessing features in the X-ray spectrum of the NELG MCG-5-23-16
I. Balestra, S. Bianchi, G. Matt
We present results from the spectral analysis of the Seyfert 1.9 galaxy MCG-5-23-16, based on ASCA, BeppoSAX, Chandra and XMM-Newton observations. The spectrum of this object shows…
The high energy emission line spectrum of NGC 1068
Giorgio Matt, Stefano Bianchi, Matteo Guainazzi +1
We present and discuss the high energy (E>4 keV) XMM-Newton spectrum of the Seyfert 2 galaxy, NGC 1068. Possible evidence for flux variability in both the neutral and ionized refle…
The HELLAS2XMM 1dF survey: on the nature of high X-ray to optical flux ratio sources
F. Fiore, M. Brusa, F. Cocchia +12
We present results from the photometric and spectroscopic identification of 122 X-ray sources discovered by XMM-Newton in the 2-10 keV band (the HELLAS2XMM 1dF sample). One of the…
Aborted jets and the X-ray emission of radio-quiet AGNs
G. Ghisellini, F. Haardt, G. Matt
We propose that radio-quiet quasars and Seyfert galaxies have central black holes powering outflows and jets which propagate only for a short distance, because the velocity of the…
Close and distant reprocessing media in Mkn509 studied with BeppoSAX
A. De Rosa, L. Piro, G. Matt +1
We present the broad band analysis of two BeppoSAX observations of the Sy 1 Mkn509. In 2000 the source was in a typical flux state, F{2-10keV}=2.7x10^{-11}erg cm^{-2} s^{-1}, while…
