Magnetic Prandtl number dependence of plasmoid-mediated reconnection
Vinay Kumar, Axel Brandenburg
We investigate the dependence of the plasmoid-mediated magnetic reconnection rate on the magnetic Prandtl number using two-dimensional magnetohydrodynamic simulations of two coales…
Resistive Scaling in the Magnetic Helicity-Driven Inverse Cascade
Jiyao Zhang, Axel Brandenburg
The inverse cascade in MHD turbulence plays a crucial role in various astrophysical processes such as galaxy cluster formation, solar and stellar dynamo mechanisms, and the evoluti…
Primordial magnetic field from chiral plasma instability with sourcing
Murman Gurgenidze, Andrew J. Long, Alberto Roper Pol +2
In an electron-positron plasma, an imbalance in the number of right- and left-chiral particles can lead to the growth of a helical magnetic field through a phenomenon called the ch…
Evidence for an Inverse Cascade of Magnetic Helicity in the Inner Heliosphere
Masatomi Iizawa, Yasuhito Narita, Tommaso Alberti +6
To elucidate the cascade direction of the solar wind turbulence, we analyzed magnetic helicity density spectra from the Parker Solar Probe data across more than 500 heliocentric di…
