X-Rays: Bursts
Scientific paper
Using two interplanetary burst network catalogues plus additional COMPTEL localizations we have selected ~60 gamma-ray bursts that can be localized to <= 0.25 square degree. We have correlated ~30 of these burst locations with the individual locations of five classes of catalogued extragalactic objects in regions of the sky with |b| > 25^deg^ where galactic obstruction effects are minimal. These objects include a total of more than 30000 individual galaxies, QSOs, rich clusters of galaxies, etc. These objects include a significant fraction of the visible matter in the universe as contained in the clusters, as well as a large sample of the most energetic objects in the universe. We find that any correlation between these catalogued objects and the gamma-ray bursts appear to be within random chance. This places significant constraints on models where the origin of these bursts is assumed to be extragalactic.
