摘要：

We perform a realistic estimate of the emission of TeV-PeV gamma rays and neutrinos by galactic matter irradiated by cosmic rays. Our calculation is directly based on profiles of matter in the galactic disk compiled by Bloemen. Our results can be compared with recent experimental limits. We investigate the consequences of hints associated with COS-B data, that cosmic ray spectrum is harder in the outer Galaxy and find that present air shower data rule out a straigtforward extrapolation of a hard spectrum up to 100 TeV. We show that we need neutrino telescopes of order 1 km(2) area to map the galaxy in TeV neutrinos.
