An anomalous positron abundance in cosmic rays with energies 1.5–100 GeV
Antiparticles account for a small fraction of cosmic rays and are known to be produced in interactions between cosmic-ray nuclei and atoms in the interstellar medium, which is referred to as aExpand
PAMELA Measurements of Cosmic-Ray Proton and Helium Spectra
Satellite measurements challenge the current understanding of cosmic-ray acceleration and propagation in our Galaxy. Protons and helium nuclei are the most abundant components of the cosmicExpand
PAMELA results on the cosmic-ray antiproton flux from 60 MeV to 180 GeV in kinetic energy.
The satellite-borne experiment PAMELA has been used to make a new measurement of the cosmic-ray antiproton flux and the antiproton-to-proton flux ratio which extends previously published measurementsExpand
Cosmic-ray electron flux measured by the PAMELA experiment between 1 and 625 GeV.
Precision measurements of the electron component in the cosmic radiation provide important information about the origin and propagation of cosmic rays in the Galaxy. Here we present new resultsExpand
Observation of an anomalous positron abundance in the cosmic radiation
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matter particleExpand
Role of sulphuric acid, ammonia and galactic cosmic rays in atmospheric aerosol nucleation
Atmospheric aerosols exert an important influence on climate through their effects on stratiform cloud albedo and lifetime and the invigoration of convective storms. Model calculations suggest thatExpand
New measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation.
A new measurement of the cosmic-ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched into low-Earth orbitExpand
Cosmic-ray positron energy spectrum measured by PAMELA.
Precision measurements of the positron component in the cosmic radiation provide important information about the propagation of cosmic rays and the nature of particle sources in our Galaxy. TheExpand
Measurement of boron and carbon fluxes in cosmic rays with the PAMELA experiment
The propagation of cosmic rays inside our galaxy plays a fundamental role in shaping their injection spectra into those observed at Earth. One of the best tools to investigate this issue is the ratioExpand
Measurement of the flux of primary cosmic ray antiprotons with energies of 60 MeV to 350 GeV in the PAMELA experiment
It is interesting to measure the antiproton galactic component in cosmic rays in order to study the mechanisms by which particles and antiparticles are generated and propagate in the Galaxy and toExpand
