The Fermi Gamma Ray Space Telescope discovers the Pulsar in the Young Galactic Supernova-Remnant CTA 1
Fermi LAT Collaboration
Energetic young pulsars and expanding blast waves (supernova remnants, SNRs) are the most visible remains after massive stars, ending their lives, explode in core-collapse supernov…
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…
The sky distribution of positronium annihilation continuum emission measured with SPI/INTEGRAL
G. Weidenspointner, C. R. Shrader, J. Knoedlseder +15
We present a measurement of the sky distribution of positronium (Ps) annihilation continuum emission obtained with the SPI spectrometer on board ESA's INTEGRAL observatory. The onl…
Spectral analysis of the Galactic e+e- annihilation emission
P. Jean, J. Knodlseder, W. Gillard +5
We present a spectral analysis of the e+e- annihilation emission from the Galactic Centre region based on the first year of measurements made with the spectrometer SPI of the INTEG…
The all-sky distribution of 511 keV electron-positron annihilation emission
J. Knödlseder, P. Jean, V. Lonjou +11
We present a map of 511 keV electron-positron annihilation emission, based on data accumulated with the SPI spectrometer aboard ESA's INTEGRAL gamma-ray observatory, that covers ap…
SPI energy calibration
V. Lonjou, J. Knodlseder, J. P. Roques +7
The status of the SPI energy calibration after the first year of INTEGRAL operations is reported. We have studied the gain variations and we have demonstrated that the most importa…
