cosmic microwave background; large-scale structure of Universe
We verify numerically that in the context of general relativity (GR), flat models which have the same Omega(m) and cosmic microwave background (CMB) shift parameter R but different H(a) and w(a) also have very similar (within less than 8 per cent) growth of perturbations even though the dark energy density evolution is quite different. This provides a direct connection between geometrical and dynamical tests of dark energy and may be used as a cosmological test of GR.
