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…
Gamma-Ray Line Emission from 7-Li and 7-Be Production by Cosmic-Rays
V. Tatischeff, J. -P. Thibaud, J. Kiener +2
We calculate the total gamma-ray line emission at ~450 keV that accompanies 7-Li and 7-Be production by cosmic-ray interactions, including the delayed line emission at 0.478 MeV fr…
INTEGRAL observations of Galaxy Clusters
P. Goldoni, A. Goldwurm, P. Laurent +3
Cluster of galaxies are the largest concentrations of visible mass in the Universe and therefore a fundamental topic of cosmology and astrophysics. Recent radio, EUV, and X-ray obs…
Lithium-Beryllium-Boron and Oxygen in the early Galaxy
Elisabeth Vangioni-Flam, Michel Casse
Oxygen is a much better evolutionary index than iron to follow the history of Lithium-Beryllium-Boron (LiBeB) since it is the main producer of these light elements at least in the…
