15. Constraining dark matter signal from a combined analysis of Milky Way satellites with the Fermi-LAT

Dwarf spheroidal galaxies are considered very promising targets for dark matter searches in the gamma-ray band due to their large mass-to-light ratio and low astrophysical background. The gamma-ray signal is expected to be very faint, but a combined analysis of a set of dwarf galaxies improves the Fermi-LAT sensitivity to gamma-ray sources and yields enhanced constraints on the dark matter...

16. A new survey technique at soft gamma-ray energies

In the view of the so-called Active Galactic Nuclei (AGN) unified model the nuclear activity is powered by a super-massive black hole (SMBH) at the center of the AGN. An optically thick gas-dust structure surrounding the SMBH absorbs efficiently the nuclear radiation. Current surveys of the INTEGRAL Soft-Gamma Ray Imager (IBIS/ISGRI) and of the Burst Alert Telescope (BAT) on board the...

ARGO-YBJ is an extensive air shower detector located in Tibet at 4300 m a.s.l. The detector features and location allow the study of gamma-ray sources with a few hundreds GeV energy threshold and very large duty cycle. Results so fare obtained will be reviewed.
