Optical identification of sources from the HELLAS2XMM survey
F. Fiore, G. Matt, F. La Franca +10
We present preliminary results on the optical identifications of sources from the High Energy Large Area Survey performed with XMM-Newton (HELLAS2XMM). This survey covers about 3 s…
Testing Comptonisation models using BeppoSAX observations of Seyfert 1 galaxies
P. O. Petrucci, F. Haardt, L. Maraschi +7
We have used realistic Comptonization models to fit high quality BeppoSAX data of 6 Seyfert galaxies. Our main effort was to adopt a Comptonization model taking into account the an…
A Self-Consistent Test of Comptonisation Models Using Bepposax Observations of Seyfert Galaxies
P. O. Petrucci, F. Haardt, L. Maraschi +6
We test accurate models of Comptonisation spectra over BeppoSAX observations of Seyfert galaxies focusing on the long look at NGC 5548. The hot plasma temperature derived with thes…
A BeppoSAX observation of 3C273: broadband spectrum and detection of a low-energy absorption feature
P. Grandi, M. Guainazzi, T. Mineo +12
We report the results of a 3C273 observation performed during the Science Verification Phase (SVP) of the BeppoSax satellite. The broad-band spectrum is well represented by a power…
