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
Can varying the gravitational constant alleviate the tensions ?
Constraints on the cosmological concordance model parameters from observables at different redshifts are usually obtained using the locally measured value of the gravitational constant GN . Here we
A new perspective on cosmology through Supernovae Ia and Gamma Ray Bursts
The actual knowledge of the structure and future evolution of our universe is based on the use of cosmological models, which can be tested through the so-called ’probes’, namely astrophysical
Do cosmological observations allow a negative $\Lambda$?
In view of the recent measurement of H0 from HST and SH0ES team, we explore the possibility of existence of a negative cosmological constant in the Universe. In this regard, we consider quintessence
Constraining a late time transition of $G_{\rm eff}$ using low-z galaxy survey data
It has recently been pointed out that a gravitational transition taking place at a recent redshift zt, reducing the effective gravitational constant Geff by about 10% for z > zt, has the potential to
On the evolution of the Hubble constant with the SNe Ia Pantheon Sample and Baryon Acoustic Oscillations: a feasibility study for GRB-cosmology in 2030
The difference from 4 to 6 σ in the Hubble constant (H0) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by

Late-time approaches to the Hubble tension deforming H(z), worsen the growth tension
Many late time approaches for the solution of the Hubble tension use a late time smooth deformation of the Hubble expansion rate H (z) of the Planck18/ΛCDM best fit H (z) to match the locally

Local determination of the Hubble constant and the deceleration parameter

Rock 'n' Roll Solutions to the Hubble Tension
Local measurements of the Hubble parameter are increasingly in tension with the value inferred from a $\Lambda$CDM fit to the cosmic microwave background (CMB) data. In this paper, we construct

Interacting scenarios with dynamical dark energy: Observational constraints and alleviation of the H0 tension
We investigate interacting scenarios which belong to a wider class, since they include a dynamical dark energy component whose equation of state follows various one-parameter parametrizations. We
