Search for Gamma Rays of Energies E > 10**15 EV from Discrete Sources
Samorski, M.; Stamm, W.
The data of the extensive air shower experiment at Kiel have been systematically scanned for possible gamma-ray sources in the energy range E > 1015eV and declination range δ = 25° - 75°. Photon fluxes for the six statistically most significant source candidates and 3 σ upper limit photon fluxes for COS B gamma-ray sources are presen…
Diffuse Galactic Emission of High Energy Gamma Rays
Hartman, R. C.; Fichtel, C. E.; Kniffen, D. A.
A study of the gamma-radiation produced by the interaction of cosmic rays with the interstellar matter and photons is extended, based on recent COS-B satellite results and background estimates (1982) and evaluations of the 21-cm radiation in the Galaxy. Gamma-ray intensities predicted over the latitude range of -10 to 10 degrees for energy ranges …
COS-B measurements of high-latitude gamma rays and evidence for a component not related to the gas.
Caraveo, P. A.; Bignami, G. F.; Strong, A. W. +7 more
The gamma ray latitude distribution for absolute value of b between 10 deg and 90 deg measured by COS-B is compared with the expected emission from cosmic-ray/gas interactions. An additional component is found which is unrelated to the gas, and which may be interpreted as a gamma-ray 'halo'. The possibility of an inverse-Compton origin is discusse…
COS-B upper limits on gamma-ray emission from radio pulsars.
Caraveo, P. A.; Bignami, G. F.; Strong, A. W. +13 more
The authors report on the results of a search for pulsed gamma-ray emission from old radio pulsars in the COS-B data in the energy range 50 MeV to 2 GeV. The analysis has been done by using either pulsar parameters obtained in simultaneous radio and gamma-ray observations or parameters which could be reliably derived by interpolation from radio ob…
