Observation of an anomalous positron abundance in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +48
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 matte…
Two years of flight of the Pamela experiment: results and perspectives
M. Casolino, Pamela Collaboration
PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range (protons: 80 MeV-700 GeV, ele…
First Results from the PAMELA Space Mission
M. Boezio, V. Bonvicini, G. Jerse +53
On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus comprises a…
A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
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 int…
Correlation between regions of star formation and gamma-ray sources
K. Belotsky, A. Galper, B. Luchkov
Statistically significant correlation between positions of unidentified gamma-ray sources (UGS) and the regions of star formation (RSF) is found. Fraction of UGS, coincided in posi…
The ALTCRISS project on board the International Space Station
M. Casolino, F. Altamura, M. Minori +19
The Altcriss project aims to perform a long term survey of the radiation environment on board the International Space Station. Measurements are being performed with active and pass…
