Comparison of multi-fluid moment models with Particle-in-Cell simulations of collisionless magnetic reconnection
Liang Wang, Ammar H. Hakim, A. Bhattacharjee +1
We introduce an extensible multi-fluid moment model in the context of collisionless magnetic reconnection. This model evolves full Maxwell equations, and simultaneously moments of…
Statistical simulation of the magnetorotational dynamo
Jonathan Squire, Amitava Bhattacharjee
Turbulence and dynamo induced by the magnetorotational instability (MRI) are analyzed using quasi-linear statistical simulation methods. It is found that homogenous turbulence is u…
Nonmodal growth of the magnetorotational instability
Jonathan Squire, Amitava Bhattacharjee
We analyze the linear growth of the magnetorotational instability (MRI) in the short time limit using nonmodal methods. Our findings are quite different to standard results, illust…
Secondary Rayleigh-Taylor type Instabilities in the Reconnection Exhaust Jet as a Mechanism for Supra-Arcade Downflows
L. -J. Guo, A. Bhattacharjee, Y. -M. Huang +1
Supra-arcade downflows (hereafter referred to as SADs) are low-emission, elongated, finger-like features usually observed in active-region coronae above post-eruption flare arcades…
Helicity-Flux-Driven Alpha Effect in Laboratory and Astrophysical Plasmas
F. Ebrahimi, A. Bhattacharjee
The constraint imposed by magnetic helicity conservation on the alpha effect is considered for both magnetically and flow dominated self-organizing plasmas. Direct numerical simula…
Observations of supra-arcade fans: instabilities at the head of reconnection jets
Davina Innes, Lijia Guo, Amitava Bhattacharjee +2
Supra-arcade fans are bright, irregular regions of emission that develop during eruptive flares, above flare arcades. The underlying flare arcades are thought to be a consequence o…
