The Intimate Link Between Accretion and BELR
F. Nicastro, A. Martocchia, G. Matt
In this paper I present evidence suggesting that the absence or presence of Hidden Broad Line Regions (HBLRs) in Seyfert 2 galaxies is regulated by the rate at which matter accrete…
Evidence for a relativistic iron line in GRS 1915+105
A. Martocchia, G. Matt, V. Karas +2
We report on the discovery of a relativistic iron Kαfluorescent emission line in the BeppoSAX spectrum of the microquasar GRS 1915+105, taken on April 19, 1998, when the line was u…
A white dwarf with a low magnetic field in the IP RXJ0028.8+5917/V709Cas
J. M. Bonnet-Bidaud, M. Mouchet, D. de Martino +2
We report the first detailed spectroscopic observations of the recently identified intermediate polar RXJ0028.8+5917/V709 Cas. We discovered that the system shows significant EW ~…
Beppo-Sax Observation of the Coma cluster
R. Fusco-Femiano, D. Dal Fiume, L. Feretti +3
We present first results of the BeppoSAX observation of the Coma Cluster. Thanks to the unprecedented sensitivity of the PDS instrument, the source has been detected up to ~80 keV.…
