Peter von Ballmoos Antimatter in the Universe is best probed through ordinary matter, the resulting annihilation-radiation providing indirect evidence for its presence. The observations of high energy (~100 MeV) gamma-rays sets limits on the fraction of nuclear antimatter contained in our local and Galactic neighbourhood. Redshifted annihilation radiation, measured in the MeV range,...

The latest results from the Alpha Magnetic Spectrometer (AMS) will be presented.

for the PAMELA collaboration. 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 primary scientific goal is the measurement of the antiproton and positron energy spectra. Antiparticles are a natural component of the cosmic radiation being produced in the interaction between cosmic...
