Can the Dynamo of Spiral-arm Galaxies Be Explained by Anisotropic Conductivity?

open access: yesThe Astrophysical Journal
The possibility of generating a magnetic field by a dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically and experimentally.

Dissecting Bar-induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications

open access: yesThe Astrophysical Journal
We analyze bars formed in N -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuthal components of stellar velocities, and the impact of bars on rotation ...
