Validation of Long-term Solar Coronal Modeling Using FORWARD

The Astrophysical Journal Supplement Series
This research aims to evaluate the capabilities of two of the most widely used coronal models over multiple solar cycles and to study variations in solar coronal structures over an extended period across multiple channels. We have created a comprehensive

Unveiling the Dynamics of Dense Cores in Cluster-forming Clumps: A 3D Magnetohydrodynamics Simulation Study of Angular Momentum and Magnetic Field Properties

The Astrophysical Journal, 2023
We conducted isothermal magnetohydrodynamics simulations with self-gravity to investigate the properties of dense cores in cluster-forming clumps. Two different setups were explored: a single rotating clump and colliding clumps. We focused on determining

Improved Myocardial Sodium Quantification at 7 T Using Interleaved 23Na/1H pTx MRI With Motion and Anatomy‐Based B1 Correction

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 173-190, July 2026.
ABSTRACT Purpose To improve accuracy and repeatability of myocardial 23Na quantification in cardiac MRI at 7 T by combining retrospective respiratory and cardiac motion correction with a novel anatomy‐based B1 bias field correction. Methods In this study, a dual‐nuclear interleaved 23Na/1H MRI sequence at 7 T was applied.

TWO-DIMENSIONAL MAGNETOHYDRODYNAMIC SIMULATIONS OF BARRED GALAXIES [PDF]

The Astrophysical Journal, 2012
Barred galaxies are known to possess magnetic fields that may affect the properties of bar substructures such as dust lanes and nuclear rings. We use two-dimensional high-resolution magnetohydrodynamic (MHD) simulations to investigate the effects of magnetic fields on the formation and evolution of such substructures as well as on the mass inflow rates

How Switchbacks Can Maintain a Longer Time in the Interplanetary Space

The Astrophysical Journal
Parker Solar Probe, the closest spacecraft to the Sun, has renewed our understanding of the solar corona and the interplanetary space. One of its important findings is the prevalence of switchbacks, which display localized magnetic reversals along the ...

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

The IllustrisTNG simulations: public data release [PDF]

, 2019
We present the full public release of all data from the TNG100 and TNG300 simulations of the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gravo-magnetohydrodynamical simulations run with the moving-mesh code Arepo.

Open Magnetic Field Lines Partition Auroral Oval Segments Into Transpolar Arcs

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Transpolar arcs (TPAs) are auroral structures spanning the polar cap. One type appears in conjugate hemispheres and is thought to be located on closed field lines, but how closed flux enters the open polar cap remains debated. We address this using observation and simulation of conjugate TPAs after an interplanetary magnetic field (IMF) By ...

Radiation-magnetohydrodynamic simulations of the photoionization of magnetized globules [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
We present the first three-dimensional radiation-magnetohydrodynamic simulations of the photoionisation of a dense, magnetised molecular globule by an external source of ultraviolet radiation. We find that, for the case of a strong ionising field, significant deviations from the non-magnetic evolution are seen when the initial magnetic field threading ...
