Hi,
Does Fig. 5 In Blake and Glazebrook (astro-ph/0301632) give a good description of future bao constraints (fractional errors) on the line-of-sight and transverse comoving distances (DA/s and sH)?
There seems to be a good concordance with the Seo and Eisenstein prediction for DA/s as seen on http://iopscience.iop.org/0004-637X/665/1/14/fulltext?ejredirect=migration but for the radial distance the behaviour looks rather different as there seems to be a noticeable local minimum at z<1 n the Blake and Glazebrook prediction which does not show up in Seo and Eisenstein.
I have produced my naïve many-body simulations to get future bao forecasts
and I agree fairly well with the two Blake and Glazebrook figures.
Hope someone with more expertise can think about this question for 10 min and give me a hint.
Best,
Ruth Lazkoz |
