Phantom crossing, equation-of-state singularities, and local gravity constraints in f(R) models
We identify the class of f(R) dark energy models which have a viable cosmology, i.e. a matter dominated epoch followed by a late-time acceleration. The deviation from a ΛCDM model (f=R−Λ) is quantified by the function m=Rf,RR/f,R. The matter epoch corresponds to m(r=−1)≃+0 (where r=−Rf,R/f) while th...
