TL;DR: High spectral resolution measurements of 26Al emission at 1808.65 keV demonstrate that the 26Al source regions corotate with the Galaxy, supporting its Galaxy-wide origin and determining a present-day equilibrium mass of 2.8 (± 0.8) solar masses of 27Al.

TL;DR: In this paper, the gamma-ray line emission from radioactive decay of 60 Fe provides constraints on nucleosynthesis in massive stars and supernovae, and the implications of these results for the widely-held hypothesis that 60 Fe is synthesized in core-collapse supernova, and also for the closely-related question of the precise origin of 26 Al in massive star.

TL;DR: In this article, the gamma-ray lines from radioactive decay of 60Fe were detected at 1173 and 1333 keV, obtaining an improvement over their earlier measurement of both lines with now 4.9 sigma significance for the combination of the two lines.

TL;DR: In this paper, the authors measured the radial velocities of gas traced by 26 Al, averaged over the line of sight, as a function of Galactic longitude, and compared these to Doppler shift expectations from large-scale systematic rotation around the Galaxy centre, as observed in other Galactic objects.

TL;DR: Diehl et al. as discussed by the authors studied the SN2014J gamma rays from the 56Ni decay chain and showed that the SN 2014J gamma ray from the decay chain can be classified as a gamma ray burst.
