Abstract
We show that a double component scenario computed in a Kraichnan-like diffusion setup (which is suggested by B/C and ¯p data) gives a satisfactory fit of the recently updated measurement of the cosmic ray electron (CRE) spectrum observed by Fermi-LAT, together with PAMELA data on positron fraction. We confirm that nearby pulsars are good source candidates for the required e± extra-component and we show that the predicted CRE anisotropy in our scenario is compatible with Fermi-LAT recently published constraints.
