Constraints on scalar-tensor models of dark energy from observational and local gravity tests
Shinji Tsujikawa, Kotub Uddin, Shuntaro Mizuno +2
We construct a family of viable scalar-tensor models of dark energy (DE) which possess a phase of late-time acceleration preceded by a standard matter era, while at the same time s…
Non-Gaussianity of the density distribution in accelerating universes II:N-body simulations
Takayuki Tatekawa, Shuntaro Mizuno
We explore the possibility of putting constraints on dark energy models with statistical property of large scale structure in the non-linear region. In particular, we investigate t…
Generalised cosmological scaling solutions
Edmund J. Copeland, Seung-Joo Lee, James E. Lidsey +1
Motivated by the recent interest in cosmologies arising from energy density modifications to the Friedmann equation, we analyse the scaling behaviour for a broad class of these cos…
Cosmological evolution of general scalar fields in a brane-world cosmology
Shuntaro Mizuno, Seung-Joo Lee, Edmund J. Copeland
We study the cosmology of a general scalar field and barotropic fluid during the early stage of a brane-world where the Friedmann constraint is dominated by the square of the energ…
