26Al kinematics: superbubbles following the spiral arms? : Constraints from the statistics of star clusters and HI supershells
Krause, Martin; Diehl, R.; Bagetakos, Y.; Brinks, E.; Burkert, A.; Gerhard, O.; Greiner, J.; Kretschmer, K.; Siegert, T. (2015-06-12)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 ... -

Kinematics of massive star ejecta in the Milky Way as traced by $^26$Al
Kretschmer, K.; Diehl, R.; Krause, Martin; Burkert, A.; Fierlinger, K.; Gerhard, O.; Greiner, J.; Wang, W. (2013-11-19)Context. Massive stars form in groups and their winds and supernova explosions create superbubbles up to kpc in size. The fate of their ejecta is of vital importance for the dynamics of the interstellar medium, for chemical ...
