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…
MGGPOD: A Monte Carlo Suite for Gamma Ray Astronomy -- Version 1.1
G. Weidenspointner, S. J. Sturner, E. I. Novikova +6
We announce the forthcoming public release of Version 1.1 of MGGPOD, a user-friendly suite of Monte Carlo codes built around the widely used GEANT (Version 3.21) package. MGGPOD is…
The sky distribution of 511 keV positron annihilation line emission as measured with INTEGRAL/SPI
G. Weidenspointner, J. Knoedlseder, P. Jean +10
The imaging spectrometer SPI on board ESA's INTEGRAL observatory provides us with an unprecedented view of positron annihilation in our Galaxy. The first sky maps in the 511 keV an…
INTEGRAL and Magnetars
D. Gotz, S. Mereghetti, K. Hurley +5
Thanks to INTEGRAL's long exposures of the Galactic Plane, the two brightest Soft Gamma-Ray Repeaters, SGR 1806-20 and SGR 1900+14, have been monitored and studied in detail for th…
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…
