摘要:

In these general remarks, we first recall that in radio astronomy, isotropy and source counts steeper than the Euclidean value of −1.5 provided early evidence for the cosmological nature of radio sources. We discuss briefly whether anything can be wrong with the evidence for isotropy and a non‐uniform distribution of GRBs. We identify the selection of cosmic GRBs among recorded bursts and their isotropy as the weaker part of the evidence. We suggest a way to relate the various ⟨V/Vmax⟩ values to each other. We point out that the strong concentrations of smallV/Vmaxvalues fits well with a uniform distribution of sources out to a redshift of about 2, but note that sources observed at these redshifts generally exhibit evolution, i.e., a non‐uniform space distribution.
