Spectroscopy Results

26Al Measurements with SPI
A scheme of the science goals: Radioactive decay as measured by INTEGRAL from 26Al decay, and the signature of Galactic rotation. The background image of the milky way is overlaid with the COMPTEL map of 26Al emission. Reference: MPE, Oct 2005

Rotation Signature
Rotation Signature: Spectra
The signature of galactic rotation, as discovered with SPI. Reference: Diehl et al., Nature, 2005

inner-Galaxy spectrum
26Al line shape as measured from the inner Galaxy with INTEGRAL. Reference: Diehl et al., A&A, 2005
