Cobe Dmr-Normalized Dark Energy Cosmogony

Likelihood analyses of the COBE Differential Microwave Radiometer (DMR) sky maps are used to determine the normalization of the inverse-power-law potential scalar-field dark energy model. Predictions of the DMR-normalized model are compared with various observations to constrain the allowed range of model parameters. Although the derived constraints are restrictive, evolving dark energy density scalar-field models remains an observationally viable alternative to the constant cosmological constant model.
