Dipole anisotropy in cosmic electrons and positrons: inspection on local sources

Understand

The cosmic electrons and positrons have been measured with unprecedented statistics up to several hundreds GeV, thus permitting to explore the role that close single sources can have in shaping the flux at different energies.

• In the present analysis, we consider electrons and positrons in cosmic rays to be produced by spallations of hadron fluxes with the interstellar medium, by a smooth Supernova Remnant (SNR) population, by all the ATNF catalog pulsars, and by few discrete, local SNRs.
• We test several source models on the $e^++e^-$ and $e^+$ AMS-02 flux data.
• For the configurations compatible with the data, we compute the dipole anisotropy in $e^++e^-$, $e^+$, $e^+/e^-$ from single sources.
