In this article, we review a series of recent theoretical results regarding a conventional
approach to the dark energy (DE) concept. This approach is distinguished among others for …

Constraining the dark energy equation of state, wx (z), is one of the main issues of current
and future cosmological surveys. In practice, this requires making assumptions about the …

Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological
distances that have emerged as prominent cosmological probes due to their dispersion …

We discuss the power of third-generation gravitational wave detectors to constrain
cosmographic parameters in the case of electromagnetically bright standard sirens focusing …

The drift in the redshift of objects passively following the cosmological expansion has long
been recognized as a key model-independent probe of cosmology. Here, we study the …

In physically realistic, scalar-field-based dynamical dark energy models (including, eg,
quintessence), one naturally expects the scalar field to couple to the rest of the model's …

The standard cosmology strongly relies upon the cosmological principle, which consists on
the hypotheses of large scale isotropy and homogeneity of the Universe. Testing these …

Abstract The Eddington-inspired-Born–Infeld scenario (EiBI) can prevent the big bang
singularity for a matter content whose equation of state is constant and positive. In a recent …

In the present paper, we investigate the cosmographic problem using the bias–variance
trade-off. We find that both the z-redshift and the y= z/(1+ z) y= z/(1+ z)-redshift can present a …

We present model independent reconstructions of quintessence and the swampland
conjectures (SC) using both machine learning (ML) and cosmography. In particular, we …
