Dissecting Pamela (and ATIC) with Occam's Razor: existing, well-known Pulsars naturally account for the "anomalous" Cosmic-Ray Electron and Positron Data

摘要: We argue that both the positron fraction measured by PAMELA and peculiar spectral features reported in total differential electron-positron flux ATIC have a very natural explanation pairs produced nearby pulsars. show greatly improved quality of current data allow us to reverse-engineer problem: given regions pulsar parameter space favored ATIC, are there known pulsars naturally explain data? address this question (1) outlining simple theoretical models for estimating energy output, diffusion setup injection index pairs, (2) considering all (as ATNF catalogue). It appears unlikely single be responsible result excess, although two sources enough experimental results. list several candidate can individually or coherently contribute data. point out Fermi-LAT will play decisive role near future, providing with an exquisite measurement make it possible distinguish between various scenarios, unveiling existence as yet undetected gamma-ray significantly local flux.
