Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

We explore whether nonstandard dark sector physics might be required to solve the existing
cosmological tensions. The properties we consider in combination are (a) an interaction …

We examine interactions between dark matter and dark energy in light of the latest
cosmological observations, focusing on a specific model with coupling proportional to the …

We investigate the observational consequences of a novel class of stable interacting dark
energy (IDE) models, featuring interactions between dark matter (DM) and dark energy (DE) …

We investigate interacting scenarios that belong to a wider class, since they include a
dynamical dark energy component whose equation of state follows various one-parameter …

The well-known tensions on the cosmological parameters H_0 H 0 and σ _8 σ 8 within the Λ
Λ CDM cosmology shown by the Planck-CMB and LSS data are possibly due to the …

In almost all interacting dark energy models present in the literature, the stability of the
model becomes potentially sensitive to the dark energy equation-of-state parameter wx, and …

Persisting tensions between high-redshift and low-redshift cosmological observations
suggest the dark energy sector of the Universe might be more complex than the positive …
