Dear all,
My talk at Mt Stromlo went very well.
Brian Schmidt of supernovae fame made a good remark. Instead of looking for peaks, which could simply require that the xi(r)'s in different z bins are similar (he thought of using a maximum likelihood technique). He was referring to Alcock & Paczynski...
Matthew Colless mentioned that both 2dF galaxies (2dFGRS) and quasars (2QZ) show a feature in P(k) at 2pi/89 h Mpc-1.
Matthew's postdoc, Roberto de Propris, showed me a plot of the correlation function of the superposition of many pencil beams drawn through the 2dFGRS. He has access to the full 250k sample, and avoided computing a complete xi(r) using all 30 billion separations. There is a feature around 250 Mpc, but there are also stronger features elsewhere, but not at 130 h-1 Mpc. It thus appears that Broadhurst et al. were lucky back in 1990.
cheers
Gary
