WebFeb 21, 2011 · The CR propagation takes place inside a cylinder—centered in the Galactic Center and oriented like the Galactic Plane—with a radius set in 20 kpc and half-thickness Lz constrained by NCR observations [6], typically it varies in the range of 1–20 kpc. The first term in Eq. (1) is related to the evolution in time. WebCosmic ray (CR) observations have much improved over the past decade leading us through a profound rethinking of their acceleration and propagation. Assuming, still, that most of the CR accelerators collectively produce a featureless power-law spectrum, we will discuss the CR propagation from a single source, that might account for the unexpected …
