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…
INTEGRAL/SPI Limits on Electron-Positron Annihilation Radiation from the Galactic Plane
B. J. Teegarden, K. Watanabe, P. Jean +24
The center of our Galaxy is a known strong source of electron-positron 511-keV annihilation radiation. Thus far, however, there have been no reliable detections of annihilation rad…
SPI/INTEGRAL observation of 1809 keV gamma-ray line emission from the Cygnus X region
J. Knödlseder, M. Valsesia, M. Allain +10
We present first results on the observation of 1809 keV gamma-ray line emission from the Cygnus X region with the SPI imaging spectrometer. Our analysis is based on data from the p…
Search for gamma-ray line emission from the radioactive decay of 60Fe with SPI
J. Knodlseder, E. Cisana, R. Diehl +11
The search for gamma-ray line emission from the radioactive decay of 60Fe figures among the prime scientific objectives of the INTEGRAL mission. 60Fe is believed to be primarily pr…
SPI/INTEGRAL in-flight performance
J. -P. Roques, S. Schanne, A. von Kienlin +23
The SPI instrument has been launched on-board the INTEGRAL observatory on October 17, 2002. SPI is a spectrometer devoted to the sky observation in the 20 keV-8 MeV energy range us…
SPI/INTEGRAL observation of the Cygnus region
L. Bouchet, E. Jourdain, J. -P. Roques +22
We present the analysis of the first observations of the Cygnus region by the SPI spectrometer onboard the Integral Gamma Ray Observatory, encompassing 600 ks of data. Thr…
