We describe a new generation gamma-ray observatory capable of
unprecedented spectroscopy over a wide range of gamma-ray energies (200
keV–50 MeV) and polarimetry (100–1000 keV). This mission was proposed to
ESA in the Cosmic Vision programme in 2008 and was presented to, but not
selected by ESA's Astronomy working group.
The primary scientific goal of the GRIPS mission is to revolutionize...

The FERMI gamma ray satellite, previously known as GLAST, is in orbit, since June 2008. After a commissioning period is now delivering data.
The Large Area Telescope (LAT), onboard of FERMI, is the most sensitive gamma-ray detector to date, in the 20 MeV - 300GeV energy band.
It provides large effective collection area(>8000cm^2@1GeV), wide field of view (>2sr) and good energy resolution...

We model the transport of cosmic ray (CR) nuclei in the Galaxy by means of a new numerical code which allows to account for a generic spatial distribution of the diffusion coefficient. We found that in the case of uniform diffusion, the main secondary/primary nuclei ratios and the modulated antiproton spectrum match consistently the available observations. We include in our analysis the...
