Abstract

High energy resolution spectroscopy of the 1.8 MeV radioactive decay line of ²⁶Al with the SPI instrument on board the INTEGRAL satellite has recently revealed that diffuse ²⁶Al has large velocities in comparison to other components of the interstellar medium in the Milky Way. ²⁶Al shows Galactic rotation in the same sense as the stars and other gas tracers, but reaches excess velocities up to 300 km s⁻¹
