Probing the Morphology of Polarized Emission Induced by Fluctuation Dynamo Using Minkowski Functionals

The Astrophysical Journal
The morphology and the characteristic scale of polarized structures provide crucial insights into the mechanisms that drive turbulence and maintain magnetic fields in magneto-ionic plasma.

Enhancement of ECCD by the current condensation effect for stabilizing large magnetic islands caused by neoclassical tearing modes in tokamak plasmas

Nuclear Fusion
The radio frequency current condensation effect reported in Reiman and Fisch (2018 Phys. Rev. Lett. 121 225001) is modeled in the nonlinear resistive magnetohydrodynamic code.

Overlapping cusp ion dispersions formed by flux ropes on the day-side magnetopause

Frontiers in Astronomy and Space Sciences
IntroductionCusp ion dispersion signatures reflect properties of remote magnetic reconnection. Since the cusp is easier to observe in situ compared to the reconnection x-line, ion dispersions provide key insight on whether reconnection is variable in ...

Continuum Reverberation in Active Galactic Nuclei Disks Only with Sufficient X-Ray Luminosity and Low Albedo

The Astrophysical Journal
Disk continuum reverberation mapping is one of the primary ways we learn about active galactic nuclei (AGN) accretion disks. Reverberation mapping assumes that time-varying X-rays incident on the accretion disk drive variability in UV–optical light ...

Active control of Alfvén eigenmodes by external magnetic perturbations with different spatial spectra

Nuclear Fusion
Alfvén eigenmodes have been suppressed and excited in tokamak plasmas by (just) modifying the poloidal spectra of externally applied static magnetic perturbations.

MHD simulations of the slow-rise phase of solar eruptions initiated from a sheared magnetic arcade [PDF]

arXiv
Before solar eruptions, a short-term slow-rise phase is often observed, during which the pre-eruption structure ascends at speeds much greater than the photospheric motions but much less than those of the eruption phase. Numerical magnetohydrodynamic (MHD) simulations of the coronal evolution driven by photospheric motions up to eruptions have been ...

Quantitative magnetohydrodynamic modelling of flux pumping in ASDEX Upgrade

Nuclear Fusion
The sawtooth-free hybrid scenario has been achieved recently in ASDEX Upgrade (AUG) with applied non-inductive current sources and auxiliary heating (Burckhart et al 2023 Nucl. Fusion 63 126056).
