Observation of an anomalous positron abundance in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +48
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matte…
Two years of flight of the Pamela experiment: results and perspectives
M. Casolino, Pamela Collaboration
PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range (protons: 80 MeV-700 GeV, ele…
PoGOLite - A High Sensitivity Balloon-Borne Soft Gamma-ray Polarimeter
Tuneyoshi Kamae, Viktor Andersson, Makoto Arimoto +36
We describe a new balloon-borne instrument (PoGOLite) capable of detecting 10% polarisation from 200mCrab point-like sources between 25 and 80keV in one 6 hour flight. Polarisation…
Measuring energy dependent polarization in soft gamma-rays using Compton scattering in PoGOLite
M. Axelsson, O. Engdegård, F. Ryde +23
Linear polarization in X- and gamma-rays is an important diagnostic of many astrophysical sources, foremost giving information about their geometry, magnetic fields, and radiation…
