Detection of Galactic Dark Matter by GLAST
A. Moiseev, J. Ormes, H. Arrighi +6
The mysterious dark matter has been a subject of special interest to high energy physicists, astrophysicists and cosmologists for many years. According to theoretical models, it ca…
Cosmic-Ray Positrons: Are There Primary Sources?
Stephane Coutu, Steven W. Barwick, James J. Beatty +15
Cosmic rays at the Earth include a secondary component originating in collisions of primary particles with the diffuse interstellar gas. The secondary cosmic rays are relatively ra…
A Search for Aperiodic Millisecond Variability in Cygnus X-1
C. Chaput, E. Bloom, L. Cominsky +7
We have conducted a search for aperiodic millisecond variability in the integrated 1 to 25 keV X-ray region of Cyg X-1. We have examined HEAO A-1 archival data and Rossi X-ray Timi…
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…
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…
