Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Search for Gravitational Waves from Scorpius X-1 in LIGO O3 Data with Corrected Orbital Ephemeris
The Astrophysical Journal, 2023 Improved observational constraints on the orbital parameters of the low-mass X-ray binary Scorpius X-1 were recently published in Killestein et al. In the process, errors were corrected in previous orbital ephemerides, which have been used in searches ...

Tests of general relativity with the binary black hole signals from the LIGO-Virgo catalog GWTC-1
, 2021 © 2019 American Physical Society. The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronomical observations and laboratory tests ...

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.This work examines the physical characteristics of charged, anisotropic compact spheres within the framework of f(R, ϕ, X) modified gravity. Starting from a static, spherically symmetric spacetime, we employ an Adler‐type ansatz for the temporal metric component gtt.

International Journal of Forestry Research, Volume 2026, Issue 1, 2026.This study explores household participation in the collection of nontimber forest products (NTFPs) in Kalu district, Northeast Ethiopia, highlighting their critical role in local livelihoods and sustainable forest management. The primary issue is the over‐reliance on and unsustainable harvesting of NTFPs by households, driven by socioeconomic needs and

Advanced Photonics Research, Volume 6, Issue 12, December 2025.Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Graviton mass bounds from an analysis of bright star trajectories at the Galactic Center
EPJ Web of Conferences, 2017 In February 2016 the LIGO & VIRGO collaboration reported the discovery of gravitational waves in merging black holes, therefore, the team confirmed GR predictions about an existence of black holes and gravitational waves in the strong gravitational field
