Observational Constraints on Interacting Model of New Agegraphic Dark Energy and Alleviation of Cosmic Age Problem
Observational Constraints on Interacting Model Agegraphic Dark Energy
2010/12/27
Many dark energy models fail to pass the cosmic age test via the old quasar APM 08279+5255 at redshift $z=3.91$, even the $\Lambda$CDM model and the holographic dark energy model are not exception. I...

Is There an Age of the Universe Problem after the Hipparcos Data?
Universe Problem Hipparcos Data
2010/4/15
We have reanalyzed the age of the universe problem under the assumption that the lower limit on the age of the globular clusters is \sim11 Gyr, as predicted by the recent Hipparcos data. We find that ...
