Multi-beam Energy Moments of Multibeam Particle Velocity Distributions
M. V. Goldman, D. L. Newman, J. P. Eastwood +1
High resolution electron and ion velocity distributions, f(v), which consist of N effectively disjoint beams, have been measured by NASA's Magnetospheric Multi-Scale Mission (MMS)…
Characterizing magnetic reconnection regions using Gaussian mixture models on particle velocity distributions
Romain Dupuis, Martin V. Goldman, David L. Newman +2
We present a method based on unsupervised machine learning to identify regions of interest using particle velocity distributions as a signature pattern. An automatic density estima…
Properties of turbulence in the reconnection exhaust: numerical simulations compared with observations
F. Pucci, S. Servidio, L. Sorriso-Valvo +6
The properties of the turbulence which develops in the outflows of magnetic reconnection have been investigated using self-consistent plasma simulations, in three dimensions. As co…
Non-linear Waves and Instabilities Leading to Secondary Reconnection in Reconnection Outflows
Giovanni Lapenta, Francesco Pucci, Vyacheslav Olshevsky +4
Reconnection outflows are regions of intense recent scrutiny, from in situ observations and from simulations. These regions are host to a variety of instabilities and intense energ…
Energy exchanges in reconnection outflows
Giovanni Lapenta, Martin V. Goldman, Davd L. Newman +1
Reconnection outflows are highly energetic directed flows that interact with the ambient plasma or with flows from other reconnection regions. Under these conditions the flow becom…
On the electron dynamics during island coalescence in asymmetric magnetic reconnection
Emanuele Cazzola, Maria Elena Innocenti, Stefano Markidis +3
We present an analysis of the electron dynamics during rapid island merging in asymmetric magnetic reconnection. We consider a doubly periodic system with two asymmetric transition…
Signatures of Secondary Collisionless Magnetic Reconnection Driven by Kink Instability of a Flux Rope
S. Markidis, G. Lapenta, G. L. Delzanno +5
The kinetic features of secondary magnetic reconnection in a single flux rope undergoing internal kink instability are studied by means of three-dimensional Particle-in-Cell simula…
Separatrices: the crux of reconnection
Giovanni Lapenta, Stefano Markidis, Andrey Divin +2
Reconnection is one of the key processes in astrophysical and laboratory plasmas: it is the opposite of a dynamo. Looking at energy, a dynamo transforms kinetic energy in magnetic…
Electromagnetic Energy Conversion in Downstream Fronts from 3D Kinetic Reconnection
Giovanni Lapenta, Martin Goldman, David Newman +2
The electromagnetic energy equation is analyzed term by term in a 3D simulation of kinetic reconnection previously reported by \citet{vapirev2013formation}. The evolution presents…
Kinetic Simulations of Plasmoid Chain Dynamics
Stefano Markidis, Pierre Henri, Giovanni Lapenta +4
The dynamics of a plasmoid chain is studied with three dimensional Particle-in-Cell simulations. The evolution of the system with and without a uniform guide field, whose strength…
Three dimensional density cavities in guide field collisionless magnetic reconnection
Stefano Markidis, Giovanni Lapenta, Andrey Divin +3
Particle-in-Cell simulations of collisionless magnetic reconnection with a guide field reveal for the first time the three dimensional features of the low density regions along the…
Collisionless magnetic reconnection in a plasmoid chain
Stefano Markidis, Pierre Henri, Giovanni Lapenta +4
The kinetic features of plasmoid chain formation and evolution are investigated by two dimensional Particle-in-Cell simulations. Magnetic reconnection is initiated in multiple X po…
Kinetic simulations of magnetic reconnection in presence of a background O+ population
Stefano Markidis, Giovanni Lapenta, Lapo Bettarini +3
Particle-in-Cell simulations of magnetic reconnection with an H+ current sheet and a mixed background plasma of H+ and O+ ions are completed using physical mass ratios. Four main r…
