RECONSTRUCTING DARK ENERGY [PDF]

open access: yesInternational Journal of Modern Physics D, 2006
This review summarizes recent attempts to reconstruct the expansion history of the universe and to probe the nature of dark energy. Reconstruction methods can be broadly classified into parametric and non-parametric approaches. It is encouraging that, even with the limited observational data currently available, different approaches give consistent ...

DYNAMICS OF DARK ENERGY

open access: yesInternational Journal of Modern Physics D, 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 progress made towards understanding the nature of dark energy. We review the observational evidence for the current accelerated expansion of the universe and

ON THE THERMODYNAMICS OF DARK ENERGY

International Journal of Modern Physics D, 2007
Recent astronomical observations suggest that the bulk of energy in the Universe is repulsive and appears like a dark energy component (which accounts for ~2/3 of the energy content of the Universe) with negative pressure (ω ≡ px/ρx < 0). In this work, we discuss the thermodynamic behavior by considering three different parametrizations, describing
