It has been intensively discussed if modifications in the dynamics of the Universe at late times is able or not to solve the H0 tension. On the other hand, it has also been argued that the H0 tension is actually a tension on the supernova absolute magnitude MB . In this work, we robustly constraintMB using Pantheon Supernovae Ia (SN) sample, Baryon Acoustic Oscillations (BAO), and Big Bang Nucleosynthesis (BBN) data, and assess the MB tension by comparing three theoretical models, namely the…

Constraints from high-precision measurements of the cosmic microwave background: the case of disintegrating dark matter with Λ or dynamical dark energy
In recent years discrepancies have emerged in measurements of the present-day rate of expansion of the universe H 0 and in estimates of the clustering of matter S 8. Using the most recent
Modified Equations of State for Dark Energy and Observational Limitations
Cosmological models with variable and modified equations of state for dark energy are confronted with observational data, including Type Ia supernovae, Hubble parameter data H(z) from different
Analytic Solutions of Scalar Field Cosmology, Mathematical Structures for Early Inflation and Late Time Accelerated Expansion
We study the most general cosmological model with real scalar field which is minimally coupled to gravity. Our calculations are based on Friedmann-Lemaitre-Robertson-Walker (FLRW) background metric.
Hubble distancing: focusing on distance measurements in cosmology
The Hubble-Lemaître tension is currently one of the most important questions in cosmology. Most of the focus so far has been on reconciling the Hubble constant value inferred from detailed cosmic

Does the Hubble constant tension call for new physics?
The Λ Cold Dark Matter model (ΛCDM) represents the current standard model in cosmology. Within this, there is a tension between the value of the Hubble constant, H0, inferred from local distance
Dark coupling
The two dark sectors of the universe dark matter and dark energy may interact with each other. Background and linear density perturbation evolution equations are developed for a generic coupling. We
Can late dark energy restore the Cosmic concordance?
The tension between inferences of Hubble constant (H0) is found in a large array of datasets combinations. Modification to the late expansion history is the most direct solution to this discrepancy.
Tale of stable interacting dark energy, observational signatures, and the H0 tension
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). In the first part
A fake interacting dark energy detection?
Models involving an interaction between the Dark Matter and the Dark Energy sectors have been proposed to alleviate the long standing Hubble constant tension. In this paper we analyze whether the
Warm decaying dark matter and the hubble tension
If a fraction of the dark matter is unstable and decays into dark radiation at around the time of matter-radiation equality, it could impact the expansion history of the universe in a way that helps
Non-linear interacting cosmological models after Planck 2018 legacy release and the H0 tension
Interacting dark energy models are widely renowned for giving an explanation to the cosmic coincidence problem as well as several observational issues. According to the recent observational data, and
