Gravitational waves confirm predicted black-hole mass gap and probe stellar nuclear physics

Published on 2026-06-01 by @NATURE

Abstract: Nature Astronomy, Published online: 01 June 2026; doi:10.1038/s41550-026-02856-zThe mass spectrum of binary black-hole mergers has been expected to show a ‘mass gap’ above 45 solar masses, consistent with the physics of pair-instability supernovae. An extensive catalogue of gravitational-wave detections reveals a high-spin population above this threshold that probably results from repeated black-hole mergers in dense star clusters, and fits with the existence of the mass gap. The inferred bo[...]


Our summary: Gravitational waves have confirmed the existence of a mass gap in binary black-hole mergers above 45 solar masses. The observed high-spin population suggests these black holes originate from repeated mergers in dense star clusters. This finding also provides insights into the carbon-to-oxygen fusion rate during helium burning in massive stars.

Accretion disk and gravitational hardening models for layered cognitive manifolds in persistent cognitive machines

Patent published on the 2026-04-16 in US under Ref US20260105260 by ATOMBEAM TECHNOLOGIES INC [US] (Galvin Brian [us])

Abstract: Systems and methods for persistence of memory on a persistent cognitive machine (PCM) that uses a continuous, differentiable, cognitive manifold in geometric space to allow a computer to engage in human-like thought processes. A PCM with cognitive manifold performs cognition on a thought manifold in a continuous, differentiable, thought manifold in geometric space as opposed to probabilistic prediction in a discontinuous, anisotropic, and topologically fractured vector space. A means for providi[...]


Our summary: The content discusses a model for persistent cognitive machines that utilize a continuous cognitive manifold for human-like thought processes. It contrasts this with traditional probabilistic methods, emphasizing a structured approach to thought layers. The model draws parallels with astrophysical concepts to explain the stability of thoughts within the cognitive framework.

Wide-mass-scanning-range setup and phase-resolved protocol for axion dark matter detection

Published on 2026-02-16 by Audrey Cottet and T Kontos @IOP SCIENCE

Abstract: We propose a paradigm for quantum enhanced axion dark matter search, which does not rely on power measurements. We propose to measure directly the axion amplitude and phase in an interferometric protocol at the quantum limit, using a non-linear cavity. In addition, we introduce gyromagnetic modes as wide mass range transducers for axion signals compatible with standard haloscope designs. We expect this scheme to offer an improvement of at least 4 orders of magnitude in figure of merit and at lea[...]


Our summary: The proposed setup enhances axion dark matter detection without relying on power measurements. It utilizes an interferometric protocol to measure axion amplitude and phase at the quantum limit. The introduction of gyromagnetic modes as transducers is expected to significantly improve detection capabilities across a wider mass range.

The Role of the Magnetic Field Orientation and Strength on the Electrodeposition of Ni-Fe Bifunctional Electrocatalyst for Hydrogen Evolution Reaction and Oxygen Evolution Reaction

Published on 2026-02-03 by Safya Elsharkawy, Mateusz M. Marzec, Piotr ?abi?ski @MDPI

Abstract: Ni&amp;ndash;Fe alloys were prepared via electrodeposition from a citrate electrolyte under different magnetic field (MF) strengths (0.1 T, 0.3 T, and 0.5 T) and configurations parallel (B&amp;#8214;) and perpendicular (B&amp;perp;) to the electrode surface. The magnetohydrodynamics (MHD) induced by the magnetic field influences their structural, compositional, and electrocatalytic properties. The application of an external homogeneous magnetic field significantly altered the alloy m[...]


Our summary: The study investigates how magnetic field orientation and strength affect the electrodeposition of Ni-Fe alloys. Results show that moderate magnetic field intensity improves film quality and electrocatalytic performance for hydrogen and oxygen evolution reactions. The findings highlight the potential to optimize bifunctional electrocatalysts through controlled magnetic field conditions.

Abstract: Detailed knowledge regarding the thermophysical properties and electrical conductivity of the combustion products derived from solid propellants is essential for the optimized design and operation of solid-fuel rocket engines employing magnetohydrodynamic drive technology. However, the high-temperature and high-pressure environment prevailing during rocket operation makes the experimental measurement of these characteristics extremely difficult, while the ionization reactions obtained by adding [...]


Our summary: This study focuses on the thermophysical properties and electrical conductivity of combustion products from solid propellants with ionization seeds. It utilizes a Gibbs free energy constraint function and Lennard-Jones potential theory to calculate specific heat, viscosity, and thermal conductivity. The numerical calculations are validated through experiments, showing a discrepancy of less than 5% in electron density at high temperatures.

Eigenvalues of the Operator Describing Magnetohydrodynamic Problems in Outer Parts of Galaxies

Published on 2026-01-15 by Evgeny Mikhailov, Tatiana Khasaeva @MDPI

Abstract: The magnetic field generation studies in astronomy lead to a number of interesting problems in mathematical physics. In the dynamo theory, the problem is reduced to a system of parabolic equations for the field components. Assuming that the field grows exponentially, we obtain an eigenvalue problem for the corresponding elliptic operator. The possibility of the field generation and behaviour of the system is characterized by the spectra of the operator. If all eigenvalues lie in the left half of[...]


Our summary: This study focuses on the eigenvalues of operators related to magnetohydrodynamic processes in galaxies. It explores the implications of these eigenvalues on the generation and behavior of galactic magnetic fields. The research employs both analytical and numerical methods to solve the eigenvalue problems associated with these operators.
