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…
Time Domain Explorations With Digital Sky Surveys
A. A. Mahabal, S. G. Djorgovski, M. J. Graham +17
One of the new frontiers of astronomical research is the exploration of time variability on the sky at different wavelengths and flux levels. We have carried out a pilot project us…
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…
Exploring the Time Domain with the Palomar-QUEST Sky Survey
A. Mahabal, S. G. Djorgovski, M. J. Graham +16
Exploration of the time variability on the sky over a broad range of flux levels and wavelengths is rapidly becoming a new frontier of astronomical research. We describe here brief…
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…
Palomar-QUEST: A case study in designing sky surveys in the VO era
Matthew J. Graham, Roy Williams, S. G. Djorgovski +10
The advent of wide-area multicolour synoptic sky surveys is leading to data sets unprecedented in size, complexity and data throughput. VO technology offers a way to exploit these…
