Soft X and Gamma ray emission from TeV sources observed with Swift and INTEGRAL
A. De Rosa, P. Ubertini, A. Bazzano +4
The soft X-ray and soft gamma observations of the new discovered TeV sources by HESS and MAGIC are crucial to discriminate between various emitting scenarios and to fully understan…
Is the INTEGRAL/IBIS source IGR J17204-3554 a gamma-ray emitting galaxy hidden behind the molecular cloud NGC 6334 ?
L. Bassani, A. De Rosa, A. Bazzano +9
We report on the identification of a soft gamma-ray source, IGR J17204-3554, detected with the IBIS imager on board the INTEGRAL satellite. The source has a 20-100 keV flux of ~3x1…
INTEGRAL IGR J18135-1751=HESS J1813-178: A new cosmic high energy accelerator from keV to TeV
P. Ubertini, L. Bassani, A. Malizia +10
We report the discovery of a soft gamma ray source, namely IGR J18135-1751, detected with the IBIS imager on board the INTEGRAL satellite. The source is persistent and has a 20-100…
A long hard look at MCG-6-30-15 with XMM-Newton
A. C. Fabian, S. Vaughan, K. Nandra +6
We present first results from a 325 ks observation of the Seyfert 1 galaxy MCG-6-30-15 with XMM-Newton and BeppoSAX. The strong, broad, skewed iron line is clearly detected and is…
The complex iron line in NGC 7469 observed by BeppoSAX
A. De Rosa, A. C. Fabian, L. Piro
In this letter we present analysis of BeppoSAX data from a long look at the Seyfert 1 galaxy NGC 7469. The presence of a soft excess below 0.8 keV is confirmed by our analysis and…
The BeppoSAX broad-band spectrum and variability of the Seyfert 1 NGC 3783
A. De Rosa, L. Piro, F. Fiore +5
BeppoSAX observed the Seyfert 1 galaxy NGC 3783 for ~ 5 days from 1998 June 6 to 1998 June 10. The average flux during the observation was F(2-10 keV) ~ 6 X 10^{-11} erg cm^-2 s^-1…
