Gaussian Process Approach for Model-independent Reconstruction of f(Q) Gravity with Direct Hubble Measurements

The Astrophysical Journal
The increase of discrepancy in the standard procedure to choose the arbitrary functional form of the Lagrangian f ( Q ) motivates us to solve this issue in modified theories of gravity. In this regard, we investigate the Gaussian process, which allows us

Impact of Teleparallelism on Addressing Current Tensions and Exploring the GW Cosmology

The Astrophysical Journal
The H _0 and S _8 tensions highlight critical discrepancies in modern cosmology, challenging the standard Lambda cold dark matter model. The H _0 tension arises from conflicting measurements between local probes and early-Universe predictions. Similarly,

Constraining Extended Teleparallel Gravity via Cosmography: A Model-independent Approach

The Astrophysical Journal
As a classical approach, the dynamics of the Universe, influenced by its dark components, are unveiled through prior modifications of Einstein’s equations.

Dark Cosmology and Its Origins

Zygon
This article reviews the standard model of cosmology: an expanding universe whose expansion is now accelerating, driven by dark energy (equivalent in practice to endowing the vacuum with a constant uniform energy density).

Trapped early dark energy

Physics Letters B
As a prospective resolution of the Hubble tension, early dark energy (EDE) suffers from the coincidence problem, why EDE is active just at matter-radiation equality (equivalently why the slope of EDE potential is required to approximately equal to the ...
