This work investigates several key aspects of a non–commutative theory with mass
deformation. We calculate thermodynamic properties of the system and compare our results …

This study focuses on investigating a regular black hole within the framework of Verlinde's
emergent gravity. In particular, we explore the main aspects of the modified Simpson–Visser …

Halometry—mapping out the spectrum, location, and kinematics of nonluminous structures
inside the Galactic halo—can be realized via variable weak gravitational lensing of the …

At present, there is a vast number of textbooks on Einstein's theory of gravity (general
relativity, GR) that are available for different kinds of readers and at different levels of …

ABSTRACT S-stars, discovered in the vicinity of the massive black hole (MBH) in the
Galactic center (GC), are anticipated to provide unique dynamical constraints on the MBH …

Modifications to the classic time-delay effect and Doppler shift in general relativity (GR) are
studied in the context of the Lorentz-violating standard-model extension (SME). We derive …

Given the extreme accuracy of modern space science, a precise relativistic modeling of
observations is required. In particular, it is important to properly describe light propagation …

This review paper discusses the science of astrometric catalogs, their current applications
and future prospects for making progress in fundamental astronomy, astrophysics and …

Classical light-bending is investigated for weak gravitational fields in the presence of
hypothetical local Lorentz violation. Using an effective field theory framework that describes …

The gravitational deflection of test particles including light, due to a radially moving Kerr–
Newman (KN) black hole with an arbitrary constant velocity that is perpendicular to its …
