Probing Dark Energy via Weak Gravitational Lensing with the SuperNova Acceleration Probe (SNAP)
SNAP Collaboration
SNAP is a candidate for the Joint Dark Energy Mission (JDEM) that seeks to place constraints on the dark energy using two distinct methods. The first, Type Ia SN, is discussed in a…
New Measurement of the Cosmic-Ray Positron Fraction from 5 to 15 GeV
J. J. Beatty, A. Bhattacharyya, C. Bower +12
We present a new measurement of the cosmic-ray positron fraction at energies between 5 and 15 GeV with the balloon-borne HEAT-pbar instrument in the spring of 2000. The data presen…
SNAP Near Infrared Detectors
G. Tarle
The SuperNova/Acceleration Probe (SNAP) will measure precisely the cosmological expansion history over both the acceleration and deceleration epochs and thereby constrain the natur…
Measurement of the Cosmic-Ray Antiproton to Proton Abundance Ratio between 4 and 50 GeV
A. S. Beach, J. J. Beatty, A. Bhattacharyya +13
We present a new measurement of the antiproton to proton abundance ratio, pbar/p, in the cosmic radiation. The HEAT-pbar instrument, a balloon borne magnet spectrometer with precis…
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…
