Spectra of dynamical Dark Energy cosmologies from constant-w models

الأصل · EN

WMAP5 and related data have greatly restricted the range of acceptable cosmologies, by providing precise likelihood ellypses on the the w₀-wₐ plane. We discuss first how such ellypses can be numerically rebuilt, and present then a map of constant-w models whose spectra, at various redshift, are expected to coincide with acceptable models within 1%.
