UniverseWe examined the Einstein–Klein–Gordon system coupled to a nonlinear electrodynamics framework that asymptotically supports a Hayward spacetime. We explored the solution space of a static, spherically symmetric, complex scalar field minimally coupled to ...

Black Hole Bounces on the Road to Quantum Gravity
Universe, 2018 Quantum resolutions of the space-time singularity at the end of gravitational collapse may provide hints towards the properties of a final theory of Quantum-Gravity.

A note on separation and compactness in categories of convergence spaces
Applied General Topology, 2003 In previous papers, various notions of compact, T3, T4, and Tychonoff objects in a topological category were introduced and compared. The main objective of this paper is to characterize each of these classes of objects in the categories of filter and ...

Prospects of Identifying Hierarchical Triple Mergers for the Third-generation Ground-based Detectors
The Astrophysical JournalA hierarchical triple merger (HTM) constitutes a type of event in which two successive black hole (BH) mergers occur sequentially within the observational window of gravitational-wave (GW) detectors, which has an important role in testing general ...

Super-Eddington Magnetized Neutron Star Accretion Flows: A Self-similar Analysis
The Astrophysical JournalThe properties of super-Eddington accretion disks exhibit substantial distinctions from the sub-Eddington ones. In this paper, we investigate the accretion process of a magnetized neutron star (NS) surrounded by a super-Eddington disk.

Nuclear Physics BThe stability of static fluid spheres with anisotropic internal stresses is studied based on the notion of complexity as defined by Herrera [1]. We show that the gradient of pressure anisotropy is intimately linked to the fluid density.

UNIVERSALITY IN MAGNETOEMISSION OF COMPACT ASTROPHYSICAL OBJECTS
Odessa Astronomical Publications, 2016 Magnetodynamics of inhomogeneous crusty nuclear matter is considered accounting for quantum fluctuations and ferromagnetic coupling. We show that anomalies in nuclide magnetic moments give rise to erratic jumps in magnetotransport of neutron star crusts.

Low-frequency Probes of the Persistent Radio Sources Associated with Repeating Fast Radio Bursts
The Astrophysical JournalThe discovery of persistent radio sources (PRSs) associated with three repeating fast radio bursts (FRBs) has provided insight into the local environments of these FRBs.

The Puzzling Long GRB 191019A: Evidence for Kilonova Light
The Astrophysical JournalGRB 191019A was a long gamma-ray burst (GRB) lasting ~65 s and, as such, originally thought to be linked to a core-collapse supernova. However, even though follow-up observations identified the optical counterpart close to the bright nucleus of a nearby ...

Charged anisotropic compact objects by gravitational decoupling
European Physical Journal C: Particles and Fields, 2018 In the present article, we have constructed a static charged anisotropic compact star model of Einstein field equations for a spherically symmetric space-time geometry.
