The 1998 outburst of the X-ray transient XTE J2012+381 as observed with BeppoSAX
S. Campana, L. Stella, T. Belloni +5
We report on the results of a series of X-ray observations of the transient black hole candidate XTE J2012+381 during the 1998 outburst performed with the BeppoSAX satellite. The o…
X-ray and optical monitoring of the peculiar source 4U 1700+24/V934 Her
N. Masetti, D. Dal Fiume, G. Cusumano +10
(Abridged) We report on ASCA and BeppoSAX observations of the X-ray source 4U 1700+24 and on (quasi-)simultaneous spectroscopy of its optical counterpart, V934 Her, from the Loiano…
Hard X-ray tails and cyclotron features in X-ray pulsars
Mauro Orlandini, Daniele Dal Fiume
We review the physical processes occurring in the magnetosphere of accreting X-ray pulsars, with emphasis on those processes that give rise to observable effects in their high (E>1…
Hard X-ray emission from the galaxy cluster A3667
R. Fusco-Femiano, D. Dal Fiume, M. Orlandini +3
We report the results of a long BeppoSAX observation of Abell 3667, one of the most spectacular galaxy cluster in the southern sky. A clear detection of hard X-ray radiation up to…
BeppoSAX study of the broad-band properties of luminous globular cluster X-ray sources
L. Sidoli, A. N. Parmar, T. Oosterbroek +4
We have performed a detailed study of the broadband spectra of the luminous globular cluster X-ray sources using BeppoSAX. With the exception of X2127+119, located in NGC7078, all…
Broad band spectrum of Cygnus X-1 in two spectral states with BeppoSAX
F. Frontera, E. Palazzi, A. A. Zdziarski +13
We report on the 0.5--200 keV spectral properties of Cyg X-1 observed at different epochs with the Narrow Field Instruments of the BeppoSAX satellite. The source was in its soft st…
