seminar at Mt Stromlo

[Gary Mamon]

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
