Nearby Galaxies in High Energy Gamma Rays
At present, there are no definitive results from nearby galaxies at photon energies above about 50 MeV. High energy gamma ray measurements of our neighboring galaxies have the potential of revealing the presence of cosmic rays as well as their density and distribution properties. These observations will have the extra advantage of being free of the complications of making the observations from within the galaxy, as is the case for our Milky Way (MW) Galaxy. In addition, such results are expected to provide new insight into many aspects of our own galaxy.
