Effect of Statistical Bin Resolution on Correlation Strength and Occurrence Maxima in Solar Wind–Ionosphere Coupling Studies
Article scientifique
Testing the running vacuum model in light of DESI-DR2 Measurements
Motivated by the fact that quantum effects leave an imprint on the vacuum equation of state, making it depart from …

Synchrotron filaments in radio galaxies: rarity, stability, and environmental influences from LOFAR and ROSAT observations
We present a systematic investigation of filamentary synchrotron structures in radio galaxies, using deep 144 MHz observations from the LOFAR …

A No-Go Theorem for Curvature Neutrality in f(Q) Cosmology?
In the framework of $f(Q)$ gravity, we investigate whether spatial curvature can be made dynamically invisible in the cosmological background …

Astro-Hunters: Machine Learning for Exoplanet Transit Detection in TESS Photometry
Finding planets beyond the Solar System is now largely a data-analysis problem: photometric surveys return far more stellar light curves …

Influence of solar, solar wind, and geomagnetic activity on the ionospheric propagation factor M(3000)F2 over Ouagadougou in the African equatorial sector
Abstract. This study examines how solar, solar wind, and geomagnetic activity influence the ionospheric propagation factor M(3000)F2 over Ouagadougou (12.4° …

Quadratic effective energy--momentum tensor on uniform-density hypersurfaces during slow-roll inflation
We investigate the quadratic-order effective energy--momentum tensor (2EMT) of scalar cosmological perturbations on uniform-density hypersurfaces during slow-roll inflation. The 2EMT …

From Cluster Cores to the Low-Density Field: Strong Environmental Quenching of Galaxy Star Formation at Low Redshift
We investigate how galaxy star formation activity depends on environment using a sample of 81,647 SDSS galaxies selected over $0.03\leq …
Article scientifique
Thermodynamic stability and geometric thermodynamics of charged black holes in Rastall-massive gravity under quintessence
In the present paper, we derive a new charged black hole solution embedded in a quintessence field within a framework …

A nutrient control on oxygenation dynamics during Earth’s Great Oxidation Episode
Earth's first rise in atmospheric oxygen occurred over a protracted period from ca. 2.43 to 2.06 billion years ago during …

Galaxy Cluster Detection and Dynamical Analysis in the VIPERS High-redshift Spectroscopic Survey
Abstract We present a dynamical analysis of galaxy clusters identified in the VIPERS spectroscopic survey within the redshift range 0.5 …
Article scientifique
A Review of How Supermassive Black Hole Binaries Can Be Detected and Characterized through Gravitational Lensing of Background Stars
Supermassive black hole binaries are an inevitable outcome of hierarchical galaxy mergers, but their sub-parsec evolutionary phase between the kpc …
Article scientifique
A Comparative Systems-Engineering Framework for RFI Coexistence in Radio Astronomy and Aviation Safety Systems
Radio astronomy and aviation safety systems occupy opposite ends of the signal-power spectrum, yet both depend on the same finite …
Article scientifique
Dynamical dark energy in the Bianchi Type-V Universe with DESI DR2 BAO, SNIa compilation and RSD measurements
We investigate the cosmological implications of dynamical dark energy (DDE) models within an anisotropic, spatially homogeneous Bianchi Type-V spacetime framework …
Article scientifique
Cosmological structure growth in energy-momentum squared gravity
We investigate the cosmological evolution of matter perturbations in the modified gravity model $f(R,T^2)$, where $T^2=T_{μν}T^{μν}$ denotes the quadratic contraction …
Article scientifique
Saturation Equations of State in Critical Gravitational Collapse: The Primordial Black Hole Threshold
The threshold and scaling laws of gravitational critical collapse depend sensitively on the matter equation of state. We investigate how …
