Dynamics of dark energy

- E. Copeland, M. Sami, S. Tsujikawa
- Physics
- 8 March 2006

We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent… Expand

f(R) Theories

- Antonio De Felice, S. Tsujikawa
- Physics, Medicine
- Living reviews in relativity
- 26 February 2010

Over the past decade, f(R) theories have been extensively studied as one of the simplest modifications to General Relativity. In this article we review various applications of f(R) theories to… Expand

J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey

- N. Benítez, R. Dupke, +149 authors L. Valdivielso
- Physics
- 20 March 2014

The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observatory in Spain with a… Expand

Inflation dynamics and reheating

- B. Bassett, S. Tsujikawa, D. Wands
- Physics
- 27 July 2005

The theory of inflation with single and multiple fields is reviewed paying particular attention to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the primary means of… Expand

Conditions for the cosmological viability of f(R) dark energy models

- L. Amendola, R. Gannouji, D. Polarski, S. Tsujikawa
- Physics
- 28 December 2006

We derive the conditions under which dark energy models whose Lagrangian densities f are written in terms of the Ricci scalar R are cosmologically viable. We show that the cosmological behavior of… Expand

Properties of singularities in the (phantom) dark energy universe

- S. Nojiri, S. Odintsov, S. Tsujikawa
- Physics
- 5 January 2005

The properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. We classify the finite-time singularities into four classes and… Expand

- Physics
- 21 April 2006

DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future Japanese space gravitational wave antenna. It aims at detecting various kinds of gravitational waves between 1 mHz and… Expand

Probing the coupling between dark components of the universe

- Z. Guo, N. Ohta, S. Tsujikawa
- Physics
- 1 February 2007

We place observational constraints on a coupling between dark energy and dark matter by using 71 Type Ia supernovae (SNe Ia) from the first year of the five-year Supernova Legacy Survey (SNLS), the… Expand
