The hard X-ray view of Giga-Hertz Peaked Spectrum Radio Galaxies
M. Guainazzi, A. Siemiginowska, C. Stanghellini +3
We present the first broadband X-ray observations of four Giga-Hertz Peaked Spectrum (GPS) radio galaxies at redshift <~1 performed by Chandra and XMM-Newton. These observations mo…
The hard X-ray view of the low-luminosity blazar in the radio galaxy NGC6251
M. Guainazzi, P. Grandi, A. Comastri +1
We present results from a BeppoSAX (July 2001) observation of the FRI radio galaxy NGC6251, together with a re-analysis of archival ASCA (October 1994) and Chandra (September 2000)…
BeppoSAX confirms extreme relativistic effects in the X-ray spectrum of MCG-6-30-15
M. Guainazzi, G. Matt, S. Molendi +8
We report the first simultaneous measure of the X-ray broadband (0.1--200 keV) continuum and of the iron K-alpha fluorescent line profile in the Seyfert 1 galaxy MCG-6-30-15. Our d…
BeppoSAX Observations of Bright Seyfert 2 Galaxies: Measuring the Intrinsic Continuum Emission
L. Bassani, M. Cappi, G. Malaguti +19
We report broad band (0.1-200 keV) X-ray observations, made by BeppoSAX, of a sample of bright Seyfert 2 galaxies: NGC7172, NGC2110, NGC4507, Mkn 3 and NGC7674. These spectra provi…
