A new measurement of the altitude dependence of the atmospheric muon intensity
J. J. Beatty, S. Coutu, S. A. Minnick +12
We present a new measurement of atmospheric muons made during an ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio mu+/mu- as a function of a…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
Weak Lensing from Space I: Instrumentation and Survey Strategy
Jason Rhodes, Alexandre Refregier, Richard Massey +1
A wide field space-based imaging telescope is necessary to fully exploit the technique of observing dark matter via weak gravitational lensing. This first paper in a three part ser…
Wide-Field Surveys from the SNAP Mission
A. Kim
The Supernova/Acceleration Probe (SNAP) is a proposed space-borne observatory that will survey the sky with a wide-field optical/near-infrared (NIR) imager. The images produced by…
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…
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…
