First result from the Alpha Magnetic Spectrometer on the International Space Station: precision measurement of the positron fraction in primary cosmic rays of 0.5-350 GeV.

M. Aguilar, +347 more
TL;DR: The very accurate data show that the positron fraction is steadily increasing from 10 to ∼ 250 GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude, showing the existence of new physical phenomena.
Journal ArticleDOI

Precision Measurement of the Proton Flux in Primary Cosmic Rays from Rigidity 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station

M. Aguilar, +294 more
TL;DR: In this paper, a precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1.GV to 1.8TV is presented based on 300 million events.
Journal ArticleDOI

Energy Spectrum of Cosmic-Ray Electrons at TeV Energies

Felix Aharonian, +155 more
TL;DR: In this measurement, the first of this type, the High Energy Stereoscopic System is able to extend the measurement of the electron spectrum beyond the range accessible to direct measurements, finding evidence for a substantial steepening in the energy spectrum above 600 GeV compared to lower energies.
Journal ArticleDOI

High Statistics Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5-500 GeV with the Alpha Magnetic Spectrometer on the International Space Station

L. Accardo, +311 more
TL;DR: The new results show, for the first time, that above ∼200 GeV the positron fraction no longer exhibits an increase with energy.
Journal ArticleDOI

Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S.

Felix Aharonian, +168 more
TL;DR: In this article, the authors present a measurement of the cosmic-ray electron spectrum with H.E.S. starting at 340 GeV and show no indication of a structure in the electron spectrum, but rather a power-law spectrum with spectral index of 3.0 +- 0.1 (stat.) + − 0.3 (syst.) which steepens at about 1 TeV.
