Higher Dimensional Dark Energy Investigation with Variable $\Lambda$ and $G$
Higher dimension variable variable G.
2010/3/17
Time variable $\Lambda$ and $G$ are studied here under a phenomenological model of $\Lambda$ through an ($n+2$) dimensional analysis. The relation of Zeldovich (1968) $|\Lambda| = 8\pi G^2m_p^6/h^4$ b...
It is very common to find numerical studies of dark energy and dark matter. Among these, one can find the interesting proposal of unifying dark matter and dark energy with the use of a single componen...

Dark Energy Models Born-Infeld Scalar Field
2010/10/15
We derive, in the large scale limit, analytical solutions for a dark energy model described by the Born-Infeld field plus a perfect fluid, both for homogeneous background and first order perturbations...
Gravitational Waves: A 100-Year Tool Applied to the Dark Energy Problem
Gravitational Waves the Dark Energy Problem
2010/10/18
Recent observations from type Ia Supernovae and from cosmic microwave background (CMB) anisotropies have revealed that most of the matter of the Universe interacts in a repulsive manner, composing the...
