Abstract Models where dark matter and dark energy interact with each other have been
proposed to solve the coincidence problem. We review the motivations underlying the need …

The discovery of the accelerating universe in the late 1990s was a watershed moment in
modern cosmology, as it indicated the presence of a fundamentally new, dominant …

ABSTRACT WMAP precision data enable accurate testing of cosmological models. We find
that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a …

We present the large-scale correlation function measured from a spectroscopic sample of
46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers …

The observational fact that the present values of the densities of dark energy and dark matter
are of the same order of magnitude, ρ _ de 0/ρ _ dm 0 ∼ O (1) ρ de 0/ρ dm 0∼ O (1), seems …

We present new determinations of the cosmic expansion history from red-envelope galaxies.
We have obtained for this purpose high-quality spectra with the Keck-LRIS spectrograph of …

Ten years ago, the discovery that the expansion of the universe is accelerating put in place
the last major building block of the present cosmological model, in which the universe is …

We review the paradigm of quintom cosmology. This scenario is motivated by the
observational indications that the equation-of-state of dark energy across the cosmological …

Mimetic gravity is a Weyl‐symmetric extension of General Relativity, related to the latter by a
singular disformal transformation, wherein the appearance of a dust‐like perfect fluid can …
