SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
The Cygnus X region - a multiwavelength view
Jürgen Knödlseder
The Cygnus X region is one of the most nearby massive star forming regions within our Galaxy, recognised by prominent emission throughout the entire electromagnetic spectrum, from…
SPI data analysis: the CESR/Toulouse approach
Jurgen Knodlseder
In order to allow for an efficient and flexible scientific analysis of data from the SPI imaging spectrometer aboard INTEGRAL, I developed a set of analysis executables that are pu…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
