Recent outcomes by the DESI Collaboration have shed light on a possible slightly evolving
dark energy, challenging the standard ΛCDM paradigm. To better understand dark energy …

The enigma of late-time cosmic acceleration (LTCA) stands as an enthralling mystery in the
realms of contemporary astrophysics and cosmology [1]. Across∗ shibesh. math@ gmail …

In the present paper, we investigate cosmological models in the most recent proposed
modified f (R, L m, T)-gravity theory in the context of a flat, homogeneous, and isotropic …

In this study, we investigate a scalar field cosmological model with Lyra's geometry to
explain the present cosmic expansion in a homogeneous and isotropic flat FRW universe. In …

We analyze time-dependent dark energy equations of state through linear and nonlinear
structure formation and their quintessence potentials, characterized by fast, recent …

This study explores five models derived from the Pacif parameterization scheme of the
Hubble parameter (H), which represent different forms of the deceleration parameter (DP) …

We examine a spherically-symmetric class of spacetimes carrying vacuum energy, while
considering the influence of an external dark energy environment represented by a non …

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

Alternative dark energy models were proposed to address the limitation of the standard
concordance model. Though different phenomenological considerations of such models are …
