Microquasars as sources of positron annihilation radiation
N. Guessoum, P. Jean, N. Prantzos
We consider the production of positrons in microquasars, i.e. X-ray binary systems that exhibit jets frequently, but not continuously. We estimate the production rate of positrons…
The sky distribution of positronium annihilation continuum emission measured with SPI/INTEGRAL
G. Weidenspointner, C. R. Shrader, J. Knoedlseder +15
We present a measurement of the sky distribution of positronium (Ps) annihilation continuum emission obtained with the SPI spectrometer on board ESA's INTEGRAL observatory. The onl…
Spectral analysis of the Galactic e+e- annihilation emission
P. Jean, J. Knodlseder, W. Gillard +5
We present a spectral analysis of the e+e- annihilation emission from the Galactic Centre region based on the first year of measurements made with the spectrometer SPI of the INTEG…
The all-sky distribution of 511 keV electron-positron annihilation emission
J. Knödlseder, P. Jean, V. Lonjou +11
We present a map of 511 keV electron-positron annihilation emission, based on data accumulated with the SPI spectrometer aboard ESA's INTEGRAL gamma-ray observatory, that covers ap…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: sky distribution
G. Weidenspointner, V. Lonjou, J. Knoedlseder +14
During its first year in orbit the INTEGRAL observatory performed deep exposures of the Galactic Center region and scanning observations of the Galactic plane. We report on the sta…
