The Hubble tension has now grown to a level of significance which can no longer be
ignored and calls for a solution which, despite a huge number of attempts, has so far eluded …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We constrain six possible extensions to the Λ cold dark matter (CDM) model using
measurements from the Dark Energy Survey's first three years of observations, alone and in …

We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

We investigate the implications of the baryon acoustic oscillations measurement released by
the Dark Energy Spectroscopic Instrument for interacting dark energy (IDE) models …

Abstract Recent Baryon Acoustic Oscillation (BAO) measurements released by DESI, when
combined with Cosmic Microwave Background (CMB) data from Planck and two different …

We critically examine the state of current constraints on the dark energy (DE) equation of
state (EoS) w. Our study is motivated by the observation that, while broadly consistent with …

We explore observational constraints on a cosmological model with an interaction between
dark energy (DE) and dark matter (DM), using a compilation of 15 measurements of the 2D …

I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

The f (Q) theories of modified gravity arise from the consideration of non-metricity as the
basic geometric quantity, and have been proven to be very efficient in describing the late …
