- Analyses of GRBs on Astronomical Emulsions. Hudec, R.; Hudcov�, V.; Krolupper, F.; Kroll, P. // AIP Conference Proceedings;2003, Vol. 662 Issue 1, p523
The millions of archival astronomical plates located at various observatories represent a unique database for various scientific projects including the GRB analyses. They can easily provide thousands of exposures for any celestial position and reach monitoring intervals of more than one year of...

- Observations of Cosmic Gamma-Ray Bursts with the Main Detector of the SIGMA Telescope onboard the Granat Observatory. Burenin, R. A.; Terekhov, O. V.; Sunyaev, R. A.; D�yachkov, A. V.; Khavenson, G.; Novikov, B. S.; Tserenin, I. D.; Sukhanov, K. M.; Goldoni, P.; Claret, A.; Goldwurm, A.; Paul, J.; Pelaez, F.; Jourdain, E.; Roques, J.-P.; Vedrenne, G. // Astronomy Letters;Jul2000, Vol. 26 Issue 7, p413
We present the observations of cosmic gamma-ray bursts (GRBs) with the main detector of the SIGMA telescope onboard the Granat Observatory from January 1990 through September 1994. The observations were carried out in the energy range 35-1300 keV. We detected 36 GRBs and 31 high-energy solar...
- Anisotropy in the Sky Distribution of Short Gamma-Ray Bursts. Litvin, V. F.; Matveev, S. A.; Mamedov, S. V.; Orlov, V. V. // Astronomy Letters;Jul2001, Vol. 27 Issue 7, p416
We analyze the sky distribution of various types of cosmic gamma-ray bursts (GRBs): short, long, and intermediate; they are determined by burst duration T[sub 90] (T[sub 90] is the time during which 90% of the burst energy is accumulated). We have found an anisotropy in the distribution of...
- Radial Distributions of Gamma-Ray Bursts and Type Ib/c Supernovae in Galaxies. Tsvetkov, D. Yu.; Blinnikov, S. I.; Pavlyuk, N. N. // Astronomy Letters;Jul2001, Vol. 27 Issue 7, p411
Data on the positions of gamma-ray bursts (GRBs) in galaxies are used to construct the radial distributions of their surface density. The gradient in GRB surface density is shown to decrease sharply at a galactocentric distance equal to the effective galactic radius. In central galactic regions,...
