Measurements of the H 0 and σ 8 parameters within the standard cosmological model
recently highlighted significant statistical tensions between the cosmic microwave …

In this paper, we consider the effects of adding curvature in extended cosmologies involving
a free-to-vary neutrino sector and different parametrizations of dark energy (DE). We make …

Phenomenological models are widely used in cosmology in relation to constraining different
cosmological models, with two common examples being cosmographic expansions and …

For the first time, we reconstruct the dark energy equation of the state parameter w from the
combination of background and perturbation observations, specifically combining the …

In this work, we use the angular diameter distances of 38 galaxy clusters with joint X-ray/SZE
observation to circumvent the circularity problem in the Amati relation for Gamma-ray Bursts …

We baseline with current cosmological observations to forecast the power of the Dark
Energy Spectroscopic Instrument (DESI) in two ways:(1) the gain in constraining power of …

In this study, we introduce a novel analytical Gaussian Process (GP) cosmography
methodology, leveraging the differentiable properties of GPs to derive key cosmological …
