The recently developed code for N-body/hydrodynamics simulations in Modified Newtonian Dynamics (MOND), known as raymond, is used to investigate the consequences of MOND on structure formation in a cosmological context, ...

A nonvanishing cosmological term in Einstein's equations implies a nonvanishing spacetime curvature even in the absence of any kind of matter. It would, in consequence, affect many of the underlying kinematic tenets of ...

Constraints on the cosmological concordance model parameters from observables at different redshifts are usually obtained using the locally measured value of the gravitational constant G(N). Here we relax this assumption, ...

We discuss the cosmological consequences of an interacting model in the dark sector in which the component evolves as a truncated power series of the Hubble parameter. We also discuss some of the thermodynamic features ...

In this work we have studied the lithium problem in nonstandard cosmological models. In particular, by using the public code alterbbn, we have included in the computation of the primordial light nuclei abundances, the ...

We investigate observational constraints on cosmological parameters combining 15 measurements of the transversal BAO scale (obtained free of any fiducial cosmology) with Planck-CMB data to explore the parametric space of ...
