Abstract:
In this paper, we examine the spatial distribution of gamma-ray bursts
(GRBs) using a sample of 373 objects. We subdivide the GRB data into
two redshift intervals over the redshift range 0<z<6.7. We measure the
two-point correlation function, ξ(r), of the GRBs. In determining
the separation distance of the GRB pairs, we consider two
representative cosmological models: a cold dark matter universe plus a
cosmological constant Λ, with
(Ωm,ΩΛ)=(0.28,0.72), and an Einstein-de Sitter
universe, with (Ωm,ΩΛ)=(1,0). We find a
z-decreasing correlation of the GRB distribution, which is in
agreement with the predictions of the current structure formation
theory. We fit a power-law model ξ(r)=(r/r0)-γ to the
measured ξ(r) and obtain an amplitude and slope of
r0=1235.2±342.6h-1Mpc and γ=0.80±0.19, respectively
(1σ confidence level), over the scales r=200-104h-1Mpc. Our
results provide a supplement to the measurement of matter correlation
on large scales, while the matter distribution below 200h-1Mpc is
usually described by the correlation function of galaxies.
