Precise GRB source locations from the renewed interplanetary network

Hurley, K.; Kouveliotou, C.; Cline, T. L. +14 more

A new interplanetary network (IPN) is made possible by the modification of the NEAR mission, now at 2 AU distance. With Ulysses and the near-Earth GRB monitors, this fully long-baseline network will produce GRB localizations at a rate of about one per week, with accuracies varying from several to tens of arc minutes. Given the delays inherent in t…

The peak flux distribution of bright gamma-ray bursts measured with ULYSSES

Hurley, K.; Atteia, J. -L.; Boër, M.

Observations of gamma-ray burst afterglows have shown that these events come from formidable explosions at cosmological distances. If the most distant GRBs seen by BATSE have redshifts of the order of 3-6 (e.g. GB 971214), it is a coincidence that the bright end of the GRB intensity distribution displays the -3/2 slope expected for a Euclidean dis…
