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...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Observational constraints Chaplygin cosmology braneworld scenario
2010/12/27
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss-Bonnet term in the ...
