We discuss an accurate measurement of the CXB in the 15-50 keV range performed with the Phoswich Detection System (PDS) instrument aboard the BeppoSAX satellite, whose results have already been recently reported elsewhere [1]. Unlike the recently reported 2-10 keV CXB measurements obtained with the imaging instruments aboard the X-ray satellites BeppoSAX, XMM-Newton, and Chandra that give CXB intensities systematically higher than those obtained with HEAO-1, using the BeppoSAX PDS pointings at high galactic latitude (|b|>15°) we measure a CXB spectrum and intensity level in the 15-50 keV energy band, which are consistent with those obtained with HEAO-1. Astrophysical consequences are discussed.

Abstract

We discuss an accurate measurement of the CXB in the 15-50 keV range performed with the Phoswich Detection System (PDS) instrument aboard the BeppoSAX satellite, whose results have already been recently reported elsewhere [1]. Unlike the recently reported 2-10 keV CXB measurements obtained with the imaging instruments aboard the X-ray satellites BeppoSAX, XMM-Newton, and Chandra that give CXB intensities systematically higher than those obtained with HEAO-1, using the BeppoSAX PDS pointings at high galactic latitude (|b|>15°) we measure a CXB spectrum and intensity level in the 15-50 keV energy band, which are consistent with those obtained with HEAO-1. Astrophysical consequences are discussed.
