Numerical modeling of laser-driven experiments aiming to demonstrate magnetic field amplification via turbulent dynamo [PDF]
, 2017 The universe is permeated by magnetic fields, with strengths ranging from a femtogauss in the voids between the filaments of galaxy clusters to several teragauss in black holes and neutron stars.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The vertical shear of horizontal neutral winds plays an important role in forming dense metallic layers in the E region. Previous studies suggest that metal ion layers may inhibit equatorial plasma bubble (EPB) development by enhancing E‐region Pedersen conductivity.

Bayesian inference methods for the calibration of stochastic dynamo models
, 2019 In essentially all applied sciences, data-driven modeling heavily relies on a sound calibration of model parameters to measured data for understanding the underlying mechanisms that lead to observed features.

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory
, 2013 The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

A basal magma ocean dynamo to explain the early lunar magnetic field
Earth and Planetary Science Letters, 2018 The source of the ancient lunar magnetic field is an unsolved problem in the Moon's evolution. Theoretical work invoking a core dynamo has been unable to explain the magnitude of the observed field, falling instead one to two orders of magnitude below it.

Constraining the Dynamo Layers in Jupiter and Saturn with Observations and Scaling Laws
The Astrophysical JournalThe dipole-dominated magnetic fields of Jupiter and Saturn provide evidence for active dynamos operating within their deep interiors, yet the depth of the convecting dynamo layers remains poorly constrained.

Turbulent 3D MHD dynamo model in spherical shells: regular oscillations of the dipolar field [PDF]
, 2010 We report the results of three-dimensional numerical simulations of convection-driven dynamos in relatively thin rotating spherical shells that show a transition from an strong non-oscillatory dipolar magnetic field to a weaker regularly oscillating ...
