Cosmic microwave background constraints on a decaying cosmological term related to the thermal evolution (2008)

Nakamura, Riou, Hashimoto, Masa-aki, Ichiki, Kiyotomo

We constrain the thermal evolution of the universe with a decaying cosmological term by using the method of the analysis for the Wilkinson Microwave Anisotropy Probe (WMAP) observation data. The...

Observational constraints on a decaying cosmological term (2006)

Nakamura, Riou, Hashimoto, Masa-aki, Ichiki, Kiyotomo

We investigate the evolution of a universe with a decaying cosmological term (vacuum energy) that is assumed to be a function of the scale factor. In this model, while the cosmological term increases...
