A Review on Resolving the Hubble Tension via Late-Universe Physics

Galaxies
The ΛCDM cosmological model has been successful in explaining many astronomical observations. However, recent observations increasingly point to deviations from the standard ΛCDM framework.

Kaniadakis Holographic Dark Energy Behavior in f(Q) Theory

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this study, the cosmological behavior of the Kaniadakis holographic dark energy model is investigated under the f(Q)$f(Q)$ theory within the framework of a flat Friedmann–Robertson–Walker (FRW) universe. The generalized holographic energy density based on Kaniadakis entropy is modeled using the Hubble horizon infrared cutoff scale, and the ...

Resolving the hubble tension: A unified approach using inhomogeneous Hu-Sawicki

Physics Letters B
The persistent 4–6 σ Hubble tension between Planck and SH0ES measurements challenges the standard ΛCDM framework. We propose a solution combining generalized inhomogeneous spacetime geometry with Hu-Sawicki F ( R ) gravity.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Axion Black Hole Solution in Non‐Metricity Gravity

Fortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract A static, spherically symmetric black hole solution in symmetric teleparallel (non‐metricity) gravity sourced by an axion field is constructed. Starting from the modified field equations, exact configurations are obtained characterized by the mass M$M$ and an axion–geometry coupling β$\beta$, with temporal metric function A(r)=1−2Mr+βr$A(r)=1-\

The Hubble Tension Resolved by the DESI Baryon Acoustic Oscillations Measurements

The Astrophysical Journal Letters
The Lambda cold dark matter (ΛCDM) cosmological model provides a good description of a wide range of astrophysical and cosmological observations. However, severe challenges to the phenomenological ΛCDM model have emerged recently, including the Hubble ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Coordinate‐ and Spacetime‐Independent Quantum Physics

Annalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity

Annalen der Physik, Volume 538, Issue 1, January 2026.
This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...
