Detectability of baryon oscillations

A comparison of the fiducial &Lambda CDM model (solid line)
with a variant of the model having no baryons (dashed line).
The dotted error bars are predictions for the 1&sigma errors in uncorrelated
bins as measurable in the SDSS Northern Polar Cap survey,
assuming the underlying model is &Lambda CDM. The smaller solid error
bars are for the Luminous Red Galaxy sample. The fiducial model has
&Omega_{0} = 0.4, &Omega_{&Lambda} = 0.6,
H_{0} = 65 km s^{-1} Mpc^{-1},
&Omega_{b} h^{2} = 0.03 and n = 1.030. The non-baryonic model
has n = 0.96, H_{0} = 56 km s^{-1} Mpc^{-1}, and
&Omega_{b} = 0. Both models are *COBE* normalised, and
divided by a matching BBKS model with &Gamma^{*} = 0.198.
(The small ``oscillations'' in the
non-baryonic model at 0.03 < k < 0.06h Mpc^{-1} are due to the
limited accuracy of the non-linear calculation at low k, and are not
physical.) (From Meiksin & White 1999, MNRAS, 304, 851.)
