Gamma-ray emission extending to energies greater than 2 GeV and lasting at least for two hours as well as 0.8–8.1 MeV nuclear line emission lasting 40 min were observed with very sensitive telescopes aboard the GAMMA and CGRO satellites for the wel

The Geminga light curve obtained with the “Gamma-1” telescope features two peaks separated by 0.5 ± 0.03 period. The light curve is pronounced for γ-quanta energies higher than 400 MeV. The pulsed flux upper limit (1σ) in the energy interval 5

Two observations of the Vela Pulsar in the energy range 50–5000 MeV performed with the GAMMA-1 telescope in 1990 and 1991 allowed us to study time variability of the pulsar light curve and energy spectra. The light curve for Eγ > 50 MeV shows defi

The gamma-ray telescope GAMMA-1 has registered gamma-emission in the range 30 – 2000 MeV from two solar flares. Spectral analysis with the use of maximum likelihood and maximum entropy methods has revealed the difference of gamma-ray production mec

The gamma-ray telescope GAMMA-1 has been operated from July 11, 1990, to February 28, 1992. During this period, the Sun was observed as a primary target several times, when its activity was on an increasing phase. Four outstanding flares were recorde

Point sources in the region of hard gamma rays 30 MeV-10 GeV were identified with single young pulsars, like Crab; transient gamma ray sources and bright quasars. The main problem in this region is the small number of the photons, registrated from th

The solar flare on March 26, 1991 presents a unique case when high energy (up to 300 MeV) gamma radiation was registered in both, impulsive and delayed, phases of the flare. The radiation in the delayed phase has been attributed to neutral pions deca

The γ‐ray emission extending to energies greater than 1.5 GeV and lasting at least for two hours was observed from the 3B/X12 two‐ribbon flare of June 15, 1991 with the telescope GAMMA‐1 aboard the GAMMA satellite. A nuclear line emission was

Two different components of γ‐emission with energies from 30 MeV to several hundred MeV were observed in the solar flare with total duration of 10 minutes. The first, impulsive one, originates as a bremsstrahlung of electrons accelerated at high p
