A number of challenges to the standard Λ CDM model have been emerging during the past few years as the accuracy of cosmological observations improves. In this review we discuss …
The simplest ΛCDM model provides a good fit to a large span of cosmological data but harbors large areas of phenomenology and ignorance. With the improvement of the number …
We consider gravity mediated by non-metricity, with vanishing curvature and torsion. The gravitational action, including an arbitrary function of the non-metric scalar, is investigated in …
The dawn of the twenty-first century came with very positive prospects for gravity, cosmology, and astrophysics. Technological progress made it possible for cosmology to enter to its …
General relativity can be formulated equivalently with a non-Riemannian geometry that associates with an affine connection of nonzero nonmetricity Q but vanishing curvature R …
In this study, we explore several new characteristics of a static anisotropic hybrid star with strange quark matter (SQM) and ordinary baryonic matter (OBM) distribution. Here, we use …
Following the recent theory of f (Q) gravity, we continue to investigate the possible existence of wormhole geometries, where Q is the non-metricity scalar. Recently, the non-metricity …
Motivated by the fact that cosmological models based on f (Q) gravity are very efficient in fitting observational datasets at both background and perturbation levels, we perform a …
Symmetric teleparallel gravity theories, in which the gravitational interaction is attributed to the nonmetricity of a flat, symmetric, but not metric-compatible affine connection, have been …
