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…
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…
Hypernovae as possible sources of Galactic positrons
Stephane Schanne, Michel Casse, Bertrand Cordier +1
INTEGRAL/SPI has recently observed a strong and extended emission resulting from electron-positron annihilation located in the Galactic center region, consistent with the Galactic…
