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…

Density perturbations in f(R) gravity theories in metric and Palatini formalisms

Shinji Tsujikawa, Kotub Uddin, Reza Tavakol

We make a detailed study of matter density perturbations in both metric and Palatini formalisms in theories whose Lagrangian density is a general function, f(R), of the Ricci scala…
