Abstract (from CDS):

Significant 1.8 MeV emission from the Cygnus region, attributed to the decay of radioactive 26Al, has been detected by COMPTEL. The COMPTEL sky-map shows diffuse, localized emission from this region with an integrated flux of (7.0±1.4).10–5photons/cm2/s at a significance level of 5σ. A study of 26Al candidate sources in the Cygnus region results in a 1.8MeV emission model that agrees well with the observed structure and intensity. Our analysis indicates that in the Cygnus region 26Al has mainly been produced by the combined nucleosynthesis activity of numerous young massive objects such as Wolf-Rayet stars and core collapse supernovae.
