Abstract: | The distribution of the sources of the Gamma-Ray Bursts (GRBs) recorded by the CGRO experiment is uniform for all directions in the sky, while the behaviour of the log N-log P suggests a space distribution of the events not homogeneous. The cosmological model can explain this result, but it cannot explain the presence of cyclotron lines in the burst energy spectra that has been observed by many experiments: the soviet KONUS experiment onboard VENERA probes, the Japanese GRBM experiment onboard GINGA satellite and, for only one candidate burst fortuitously observed, by the USA experiment A4 onboard HEAO1 satellite. In order to shed more light on this problem we present a new study of the log N-log P of the Gamma-Ray Bursts of the second BATSE catalogue. |
