Role of Parallel Solenoidal Electric Field on Energy Conversion in 2.5D Decaying Turbulence with a Guide Magnetic Field
Peera Pongkitiwanichakul, David Ruffolo, Fan Guo +5
We perform 2.5D particle-in-cell simulations of decaying turbulence in the presence of a guide (out-of-plane) background magnetic field. The fluctuating magnetic field initially co…
Cosmic ray Transport in Magnetohydrodynamic turbulence
Snehanshu Maiti, Kirit Makwana, Heshou Zhang +1
This paper studies cosmic ray (CR) transport in magneto hydrodynamic (MHD) turbulence. CR transport is strongly dependent on the properties of the magnetic turbulence. We perform t…
Ideal MHD instabilities for coronal mass ejections
Rony Keppens, Yang Guo, Kirit Makwana +4
We review and discuss insights on ideal magnetohydrodynamic (MHD) instabilities that can play a role in destabilizing solar coronal flux rope structures. For single flux ropes, fai…
Identification of plasma modes in Galactic turbulence with synchrotron polarization
Heshou Zhang, Alexey Chepurnov, Huirong Yan +3
Magneto-hydrodynamic (MHD) turbulence is ubiquitous and a fundamental ingredient underlying many astrophysical phenomena. The multiphase nature of interstellar medium and diversity…
Two-way coupling of magnetohydrodynamic simulations with embedded particle-in-cell simulations
Kirit Makwana, Rony Keppens, Giovanni Lapenta
We describe a method for coupling an embedded domain in a magnetohydrodynamic (MHD) simulation with a particle-in-cell (PIC) method. In this two-way coupling we follow the work of…
Dissipation in PIC simulations of moderate to low \b{eta} plasma turbulence
Kirit Makwana, Hui Li, Fan Guo +1
We simulate decaying turbulence in electron-positron pair plasmas using a fully- kinetic particle-in-cell (PIC) code. We run two simulations with moderate-to-low plasma beta. The e…
Energy dynamics and current sheet structure in fluid and kinetic simulations of decaying magnetohydrodynamic turbulence
K. D. Makwana, V. Zhdankin, H. Li +2
Simulations of decaying magnetohydrodynamic (MHD) turbulence are performed with a fluid and a kinetic code. The initial condition is an ensemble of long-wavelength, counter-propaga…
