First results from the IllustrisTNG simulations: the galaxy colour bimodality

open access: yes, 2018
We introduce the first two simulations of the IllustrisTNG project, a next generation of cosmological magnetohydrodynamical simulations, focusing on the optical colours of galaxies.

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

open access: yesEnergy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

A Coscaling Grid for Athena++. II. Magnetohydrodynamics

open access: yesThe Astrophysical Journal Supplement Series
We extend the coscaling formalism of Habegger & Heitsch implemented in Athena++ to magnetohydrodynamics. The formalism relies on flow symmetries in astrophysical problems involving expansion, contraction, and center-of-mass motion. The formalism is fully

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Existence and uniqueness in critical spaces for the magnetohydrodynamical system in R n

open access: yes, 2022
We give a description of a magnetohydrodynamical system in n dimension using the exterior derivative. We then prove existence of global solutions for small initial data and local existence for arbitrary large data in two classes of critical spaces-L q t ...

Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

open access: yesHigh Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

Nightside Auroral Arcs Near the Electron Isotropy Boundary: TRACERS–THEMIS–MetOp Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Particle precipitation is the ultimate driver of aurorae. Monoenergetic (∼keV) electrons accelerated above the ionosphere produce discrete auroral forms and are associated with field‐aligned currents that govern magnetosphere–ionosphere (MI) coupling.

The Galaxy Stellar Mass–Star Formation Rate–Size Relation in EAGLE, TNG100, and Observations

open access: yesThe Astrophysical Journal
The stellar mass, size, and star formation rate (SFR) are fundamental properties that encode the structural and evolutionary states of galaxies. Observations reveal a mass–SFR–size relation, whereby galaxies become more compact both above and below the ...

Enhanced Electromagnetic Cooling using Ethylene Glycol‐Based Sutterby Tri‐Hybrid Nanofluid Over a Riga Plate

open access: yesEngineering Reports, Volume 8, Issue 11, November 2026.
As the thermal demands of automotive radiators and electronic cooling systems continue to grow, it is imperative to develop advanced heat transfer fluids that possess better thermo physical properties. Current work focuses on the hydrodynamic and thermal behavior of a tri‐hybrid nanofluid formulated with ethylene glycol as the base fluid (CuO‐Al2O3 ...

A simulation of the IPS variations from a magnetohydrodynamical simulation [PDF]

open access: yes, 1987
Calculations of the variations of interplanetary scintillation (IPS) from a disturbance simulated by a 3-D magnetohydrodynamical (MHD) model of the solar wind are presented.
