Some problems of the detection of the high energy gamma-radiation in space

Fradkin, M. I.; Ginzburg, V. L.; Kurnosova, L. V. +8 more

The flux of the diffuse gamma-radiation in the Galaxy was measured with the instruments on board of the satellites COS-B and Compton Gamma Ray Observatory (CGRO). It was shown that the spectrum of the diffuse gamma-rays N(E) in the energy range from very low energy (some tens keV) up to some GeV may be represented by the expression N(E) = AE^kdE, …

A new γ-ray pulsar: PSR 0740-28

Lu, Tan; Ma, Yu-qian; Song, Li-ming

We made a period folding analysis on two sets of COS-B observations and obtained a clearly pulsed phase structure in the γ-ray photons from the direction of PSR 0740-28. The phase diagrams from the two different data sets have a similar structure and the period and period rate are close to radio expectations. The probability of the two phase struc…
