Radial velocity map and line profiles of 26Al emission from Galactic rotation.

GEHRELS N. and CHEN W.

Abstract (from CDS):

Based on our spiral-arm model of the COMPTEL 26Al map features, the 1.8MeV line centroid from individual hot spots will be shifted due to Galactic rotation. We present a 21-cm style radial velocity map of our model 26Al distribution and calculate the model line profiles from some of the candidate spiral arm directions. The INTEGRAL, with its fine energy resolution, will help solve the 26Al problem by accurately measuring the line centroid and so identifying the true locations of the hot spots, especially in the poorly understood inner Galaxy and Galactic center regions.
