The BeppoSAX High Energy Large Area Survey HELLAS, III: testing synthesis models for the X-ray background
A. Comastri, F. Fiore, C. Vignali +3
The BeppoSAX High Energy Large Area Survey (HELLAS) has surveyed several tens of square degrees of the sky in the 5--10 keV band down to a flux of about 5 10^-14 erg cm-2 s-1. The…
The BeppoSAX High Energy Large Area Survey HELLAS, II: Number counts and X-ray spectral properties
F. Fiore, P. Giommi, C. Vignali +7
The BeppoSAX High Energy Large Area Survey (HELLAS) has surveyed about 85 deg^2 of sky in the 5-10 keV band down to a flux of 4-5 10^-14 erg cm-2 s-1. The source surface density of…
The discovery of quiescent X-ray emission from SAX J1808.4-3658, the transient 2.5ms pulsar
L. Stella, S. Campana, S. Mereghetti +2
We report on a 20 ks BeppoSAX observation of the transient 2.5 ms X-ray pulsar SAX J1808.4-3658 in its quiescent state. A source at a level of ~ 3 x 10^-3 c/s was detected with the…
BeppoSAX and Chandra Observations of SAXJ0103.2-7209=2E0101.5-7225: a new Persistent 345s X-ray Pulsar in the SMC
G. L. Israel, S. Campana, S. Covino +8
We report the results of a 1998 July BeppoSAX observation of a field in the SMC which led to the discovery of 345s pulsations in the X-ray flux of SAXJ0103.2-7209. The BeppoSAX X-r…
The 0.1-100 keV spectral shape and variability of Mkn421 in high state
A. Malizia, M. Capalbi, F. Fiore +15
The results of a BeppoSAX TOO observation of the BL Lac object Mkn421 during a high intensity state are reported and compared with monitoring X-ray data collected with the BeppoSAX…
BeppoSAX LECS background subtraction techniques
A. N. Parmar, T. Oosterbroek, A. Orr +5
We present 3 methods for the subtraction of non-cosmic and unresolved cosmic backgrounds observed by the Low-Energy Concentrator Spectrometer (LECS) on-board BeppoSAX. Removal of t…
