Reconnection in a weakly stochastic field

- A. Lazarian, E. Vishniac
- Physics
- 3 November 1998

We examine the effect of weak, small-scale magnetic field structure on the rate of reconnection in a strongly magnetized plasma. This affects the rate of reconnection by reducing the transverse scale… Expand

The Anisotropy of Magnetohydrodynamic Alfvénic Turbulence

- Jungyeon Cho, E. Vishniac
- Physics
- 10 August 2000

We perform direct three-dimensional numerical simulations for magnetohydrodynamic (MHD) turbulence in a periodic box of size 2π threaded by strong uniform magnetic fields. We use a pseudospectral… Expand

NONLINEAR INSTABILITIES IN SHOCK-BOUNDED SLABS

- E. Vishniac
- Physics
- 24 June 1993

(substantial changes to section 3.2, otherwise minor) We present an analysis of the hydrodynamic stability of a cold slab bounded by two accretion shocks. Previous numerical work has shown that when… Expand

The dynamic and gravitational instabilities of spherical shocks

- E. Vishniac
- Physics
- 1 November 1983

In this paper we examine the stability of a thin spherical shock against dynamic and gravitational perturbations when the wavelength of the perturbation is large compared to the thickness of the… Expand

Simulations of Magnetohydrodynamic Turbulence in a Strongly Magnetized Medium

- Jungyeon Cho, A. Lazarian, E. Vishniac
- Physics
- 14 May 2001

We analyze three-dimensional numerical simulations of driven incompressible magnetohydrodynamic (MHD) turbulence in a periodic box threaded by a moderately strong external magnetic field. We sum over… Expand

The Anisotropy of MHD Alfv\'{e}nic Turbulence

- Jungyeon Cho, E. Vishniac
- Physics
- 27 March 2000

We perform direct 3-dimensional numerical simulations for magnetohydrodynamic (MHD) turbulence in a periodic box of size $2\pi$ threaded by strong uniform magnetic fields. We use a pseudo-spectral… Expand

GROWTH OF MAGNETIC FIELDS INDUCED BY TURBULENT MOTIONS

- J. Cho, E. Vishniac, A. Beresnyak, A. Lazarian, D. Ryu
- Physics
- 3 December 2008

We present numerical simulations of driven magnetohydrodynamic (MHD) turbulence with weak/moderate imposed magnetic fields. The main goal is to clarify dynamics of magnetic field growth. We also… Expand

Reionization and small-scale fluctuations in the microwave background

- E. Vishniac
- Physics
- 1 November 1987

It is shown that electron scattering off the moving ionized medium can regenerate arcminute fluctuations in almost all models of galaxy formation. Explicit calculations are presented for… Expand

NUMERICAL TESTS OF FAST RECONNECTION IN WEAKLY STOCHASTIC MAGNETIC FIELDS

- G. Kowal, A. Lazarian, E. Vishniac, K. Otmianowska-Mazur
- Physics
- 11 March 2009

We study the effects of turbulence on magnetic reconnection using three-dimensional direct numerical simulations. This is the first attempt to test a model of fast magnetic reconnection in the… Expand

Magnetic Helicity Conservation and Astrophysical Dynamos

- E. Vishniac, Jungyeon Cho
- Physics
- 18 October 2000

We construct a magnetic helicity conserving dynamo theory that incorporates a calculated magnetic helicity current. In this model the fluid helicity plays a small role in large-scale magnetic field… Expand
