The last Gift of BeppoSAX: PDS Observations of the two Blazars 1ES 0507-040 and PKS 1229-021
L. Chiappetti, G. Ghisellini, L. Maraschi +4
Towards the end of the BeppoSAX mission, the only operated Narrow Field Instrument was the PDS, which covers the energy range 13-300 keV. Two blazars, 1ES 0507-040 (z=0.304) and PK…
The X-ray spectrum of the black hole candidate GX339-4 in a low state
A. Corongiu, L. Chiappetti, F. Haardt +3
We report on four observations of the black hole candidate GX 339-4 collected in the spectral range 0.4-140 keV with the BeppoSAX satellite during 1997. All our spectra are typical…
The XMM-LSS survey. Survey design and first results
M. Pierre, I. Valtchanov, B. Altieri +36
We have designed a medium deep large area X-ray survey with XMM - the XMM Large Scale Structure survey, XMM-LSS - with the scope of extending the cosmological tests attempted using…
