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…

Periodic modulation of the optical counterpart of the X-ray pulsator 1WGA J1958.2+3232. A new intermediate polar
M. Uslenghi, P. Bergamini, S. Catalano +2
Time-resolved observations of a 6' x 6' field, containing the position error boxes of the X-ray source 1WGA J1958.2+3232, were performed in June 1999 with the 91 cm Catania telesco…
