Superbubbles, Galactic Dynamos and the Spike Instability
Russell M. Kulsrud
We draw attention to a problem with the alpha-Omega dynamo when it is applied to the origin of the galactic magnetic field under the assumption of perfect flux freezing. The standa…
The Galactic Dynamo and Superbubbles
Russell M. Kulsrud
In previous galactic dynamo theories of the origin of the magnetic field in our galaxy, the subject of flux-freezing has been omitted. As a consequence, the equation of mass flow h…
Plasmoid solutions of the Hahm--Kulsrud--Taylor equilibrium model
R. L. Dewar, A. Bhattacharjee, R. M. Kulsrud +1
The Hahm--Kulsrud (HK) [T. S. Hahm and R. M. Kulsrud, Phys. Fluids {\bf 28}, 2412 (1985)] solutions for a magnetically sheared plasma slab driven by a resonant periodic boundary pe…
Nonlinear growth of firehose and mirror fluctuations in turbulent galaxy-cluster plasmas
A. A. Schekochihin, S. C. Cowley, R. M. Kulsrud +2
In turbulent high-beta astrophysical plasmas (exemplified by the galaxy cluster plasmas), pressure-anisotropy-driven firehose and mirror fluctuations grow nonlinearly to large ampl…
An Obliquely Propagating Electromagnetic Drift Instability in the Lower Hybrid Frequency Range
Hantao Ji, Russell Kulsrud, William Fox +1
By employing a local two-fluid theory, we investigate an obliquely propagating electromagnetic instability in the lower hybrid frequency range driven by cross-field current or rela…
On the two-dimensional magnetic reconnection with nonuniform resistivity
Leonid Malyshkin, Russell M. Kulsrud
In this paper two theoretical approaches for the calculation of the rate of quasi-stationary, two-dimensional magnetic reconnection with nonuniform anomalous resistivity are consid…
