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…
Hypernovae and light dark matter as possible Galactic positron sources
S. Schanne, M. Casse, J. Paul +1
The electron-positron annihilation source in the Galactic center region has recently been observed with INTEGRAL/SPI, which shows that this 511 keV source is strong and its extensi…
Search for 44Ti gamma-ray line emission from GRO J0852-4642 with INTEGRAL/SPI
A. von Kienlin, D. Attie, S. Schanne +7
The gamma-ray source GRO J0852-4642, discovered by COMPTEL, is a possible counterpart of the supernova remnant RX J0852-4622. Detection of radioactive decay from 44Ti nuclei would…
The INTEGRAL/SPI response and the Crab observations
P. Sizun, C. R. Shrader, D. Attie +8
The Crab region was observed several times by INTEGRAL for calibration purposes. This paper aims at underlining the systematic interactions between (i) observations of this referen…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
Search for a light dark matter annihilation signal in the Sagittarius Dwarf Galaxy
B. Cordier, D. Attie, M. Casse +6
The 511 keV emission from the Galactic Bulge observed by INTEGRAL/SPI could be the product of light (1-100 MeV) annihilating dark matter particles. In order to distinguish between…
