Anisotropy of Cosmic Elementary particles measured with the Alpha Magnetic Spectrometer on the ISS

The analysis of anisotropy of the arrival directions of galactic positrons, electrons and protons has been performed with the Alpha Magnetic Spectrometer on the International Space Station. This measurement allows to differentiate between point-like and diffuse sources of cosmic rays for the understanding of the origin of high energy positrons and electrons or the hardening in the proton flux. The AMS results of the dipole anisotropy are presented along with the discussion of the implications of these measurements.

Abstract

The analysis of anisotropy of the arrival directions of galactic positrons, electrons and protons has been performed with the Alpha Magnetic Spectrometer on the International Space Station. This measurement allows to differentiate between point-like and diffuse sources of cosmic rays for the understanding of the origin of high energy positrons and electrons or the hardening in the proton flux. The AMS results of the dipole anisotropy are presented along with the discussion of the implications of these measurements.
