The sky distribution of 511 keV positron annihilation line emission as measured with INTEGRAL/SPI
G. Weidenspointner, J. Knoedlseder, P. Jean +10
The imaging spectrometer SPI on board ESA's INTEGRAL observatory provides us with an unprecedented view of positron annihilation in our Galaxy. The first sky maps in the 511 keV an…
Exploring the Hard X-/soft gamma-ray Continuum Spectra with Laue Lenses
F. Frontera, A. Pisa, P. De Chiara +17
The history of X-ray astronomy has shown that any advancement in our knowledge of the X-ray sky is strictly related to an increase in instrument sensitivity. At energies above 60 k…
SPI energy calibration
V. Lonjou, J. Knodlseder, J. P. Roques +7
The status of the SPI energy calibration after the first year of INTEGRAL operations is reported. We have studied the gain variations and we have demonstrated that the most importa…
The Cygnus X region: a nucleosynthesis laboratory for INTEGRAL
J. Knodlseder, M. Cervino, D. Schaerer +2
The detection of 1.809 MeV gamma-ray line emission from the Cygnus X complex by the COMPTEL telescope is one of the most convincing proves of massive star nucleosynthesis in our Ga…
Gamma-ray line emission from OB associations and young open clusters: I. Evolutionary synthesis models
M. Cervino, J. Knodlseder, D. Schaerer +2
We have developed a new diagnostic tool for the study of gamma-ray emission lines from radioactive isotopes (such as 26Al and 60Fe in conjunction with other multi-wavelength observ…
