Beschreibung:
We compare the burst distribution of the Burst and Transient Source Experiment (BATSE)-2B catalog to a cosmological distribution. The observed distribution agrees well with a cosmological one, however, it is insensitive to cosmological parameters such as omega and lambda. The bursts are not necessarily standard candles, and their luminosity can vary by up to a factor of 10. The maximal redshift, z(sub max), of bursts longer than 2 s is 2.1(sup +1)(sub -0.7) (assuming no evolution). The present data is insufficient to determine maximal redshift, z(sub max), of bursts shorter than 2 s.
