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…
Integral and Light Dark Matter
M. Casse, P. Fayet, S. Schanne +2
The nature of Dark Matter remains one of the outstanding questions of modern astrophysics. The success of the Cold Dark Matter cosmological model argues strongly in favor of a majo…
