We present the evolution of the structure of relaxed cold dark matter haloes in the cosmology from the Planck satellite. Our… Expand We investigate the cosmological perturbations in f(T) gravity. Examining the pure gravitational perturbations in the scalar… Expand We propose a model for a power-counting renormalizable field theory living in a fractal spacetime. The action is Lorentz… Expand We review the paradigm of quintom cosmology. This scenario is motivated by the observational indications that the equation of… Expand Abstract We consider the recently proposed non-relativistic Hořava–Lifshitz four-dimensional theory of gravity. We study a… Expand We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo… Expand In this paper, we present a new scenario of the early universe that contains a pre-big bang ekpyrotic phase. By combining this… Expand We develop the general scheme for modified f(R) gravity reconstruction from any realistic Friedmann-Robertson-Walker (FRW… Expand In the local Universe, most galaxies are dominated by stars, with less than ten per cent of their visible mass in the form of gas… Expand Staying within an objectual interpretation of the quantifiers, perhaps the simplest way to make systematic sense of expressions… Expand
