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 …

Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

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 …

Exploring the recent expansion history of the universe promises insights into the
cosmological model, the nature of dark energy, and potentially clues to high energy physics …

We explore cosmological constraints on the sum of the three active neutrino masses M ν in
the context of dynamical dark energy (DDE) models with equation of state (EoS) …

We show that cosmic acceleration can arise due to very tiny corrections to the usual
gravitational action of general relativity, of the form R− n with n> 0. This model eliminates the …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

We develop a formalism to characterize the shape and the redshift evolution of the dark
energy potential. Our formalism makes use of quantities similar to the horizon-flow …
