Imaging the Gamma-Ray Sky with SPI aboard INTEGRAL

Jürgen Knödlseder, Georg Weidenspointner, Pierre Jean +6

The spectrometer SPI on INTEGRAL allows for the first time simultaneous imaging of diffuse and point-like emission in the hard X-ray and soft gamma-ray regime. To fully exploit the…

Soft gamma-ray galactic ridge emission as unveiled by SPI aboard INTEGRAL

Jürgen Knödlseder, Vincent Lonjou, Georg Weidenspointner +6

The origin of the soft gamma-ray (200 keV - 1 MeV) galactic ridge emission is one of the long-standing mysteries in the field of high-energy astrophysics. Population studies at low…

SPI/INTEGRAL observation of 1809 keV gamma-ray line emission from the Cygnus X region

J. Knödlseder, M. Valsesia, M. Allain +10

We present first results on the observation of 1809 keV gamma-ray line emission from the Cygnus X region with the SPI imaging spectrometer. Our analysis is based on data from the p…
