We investigate the cosmological solutions of f (R, T) modified theories of gravity for a perfect
fluid in a spatially Friedmann-Lemaître-Robertson-Walker metric through the phase-space …

We present a general relativistic description of galaxy clustering in a Friedmann-Lemaître-
Robertson-Walker universe. The observed redshift and position of galaxies are affected by …

Theoretical approaches to explaining the observed acceleration of the universe are
reviewed. We briefly discuss the evidence for cosmic acceleration, and the implications for …

We present limits on the parameters of the o Λ CDM, w 0 CDM, and w 0 wa CDM models
obtained from the joint analysis of the full-shape, baryon acoustic oscillations (BAO), big …

Modifications of general relativity provide an alternative explanation to dark energy for the
observed acceleration of the universe. We review recent developments in modified gravity …

We study the nonlinear evolution of baryon acoustic oscillations in the dark matter power
spectrum and the correlation function using renormalized perturbation theory. In a previous …

The free streaming of warm dark matter particles dampens the fluctuation spectrum, flattens
the mass function of haloes and sets a fine-grained phase density limit for dark matter …

The standard cosmological model is based on general relativity and includes dark matter
and dark energy. An important prediction of this model is a fixed relationship between the …

We have used the E p, i–E iso correlation of gamma-ray bursts (GRBs) to measure the
cosmological parameter ΩM. By adopting a maximum likelihood approach which allows us …

We present a new method that simultaneously solves for cosmology and galaxy bias on non-
linear scales. The method uses the halo model to analytically describe the (non-linear) …
