Fast Timing Analysis of Cygnus X-1 using SPI on board INTEGRAL
Analysis Cygnus board INTEGRAL
2011/9/29
For the very first time, we report the high frequency analysis of Cyg X-1 up to hard X-ray using SPI on-board INTEGRAL. After analyzing the possible contribution fromthe background, and using INTEGRAL...
Diffuse emission measurement with INTEGRAL/SPI as indirect probe of cosmic-ray electrons and positrons
Galaxy: general ?Galaxy structure ?gamma rays observations
2011/8/24
Significant advances have been made in the understanding of the diffuse Galactic hard X-ray continuum emission using data from the INTEGRAL observatory. The diffuse hard power-law component seen with ...
