We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

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 …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

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 …

We introduce two new diagnostics of dark energy (DE). The first, O m, is a combination of the
Hubble parameter and the cosmological redshift and provides a null test of dark energy …

We explore nonlocally modified models of gravity, inspired by quantum loop corrections, as
a mechanism for explaining current cosmic acceleration. These theories enjoy two major …

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 …

We investigate models of interacting dark matter and dark energy for the Universe in a
spatially flat Friedmann-Robertson-Walker space-time. We find the “source equation” for the …

We consider the reconstruction technique in theories with a single or multiple (phantom
and/or canonical) scalar fields. With the help of several examples, it is demonstrated …
