Are gamma-ray bursters in our galaxy? Academic Article uri icon

abstract

  • The possibility is considered that the intrinsic luminosity function of gamma-ray bursters has sufficient scatter to dominate geometric effects in the apparent luminosity distribution. It is shown that the distribution of bursts on the sky would then be very granular, with a significant fraction of them coming from the two or three nearest sources. Moreover, the intrinsic luminosity function that minimizes granularity without producing significant dislike anisotropy yields an average value of V/Vmax that is larger than observed. Possible alternatives are briefly discussed.
