The Energy Spectra and Relative Abundances of Electrons and Positrons in the Galactic Cosmic Radiation
S. W. Barwick, J. J. Beatty, C. R. Bower +17
Observations of cosmic-ray electrons and positrons have been made with a new balloon-borne detector, HEAT (the "High-Energy Antimatter Telescope"), first flown in 1994 May from For…
Constraints on the Intergalactic Transport of Cosmic Rays
Fred C. Adams, Katherine Freese, Gregory Laughlin +2
Motivated by recent experimental proposals to search for extragalactic cosmic rays (including anti-matter from distant galaxies), we study particle propagation through the intergal…
Measurements of the Cosmic-Ray Positron Fraction From 1 to 50 GeV
HEAT Collaboration, S. W. Barwick, E. Schneider +16
Two measurements of the cosmic-ray positron fraction as a function of energy have been made using the High Energy Antimatter Telescope (HEAT) balloon-borne instrument. The first fl…
