Identifying the electron diffusion region in a realistic simulation of Earth's magnetotail
Geophysical Research Letters, 2016 A historic challenge to understanding geomagnetic activity is determining where in Earth's magnetotail magnetic energy is converted into particle energy and heat by magnetic reconnection.

Effect of interchange instability on magnetic reconnection [PDF]
Nonlinear Processes in Geophysics, 2013 We present here the results of a study of interacting magnetic fields that involves a force normal to the reconnection layer. In the presence of such force, the reconnection layer becomes unstable to interchange disturbances.

Waves Generated by Electron Beam in a Crater-Shaped Flux Rope
Frontiers in Physics, 2021 Understanding the nature and characteristics of high-frequency waves inside a flux rope may be important as the wave-particle interaction is important for charged-particle energization and the ensuing dissipation process. We analyze waves generated by an

Relationship Between Geomagnetic Storms and Auroral/Magnetospheric Substorms: Early Studies
Frontiers in Astronomy and Space Sciences, 2020 This paper describes a short story of how I learned in early days in space physics (1960–1970) that there are the direct and feed-back relationships between geomagnetic storms and auroral/magnetospheric substorms.

Juno Observations of Ion‐Inertial Scale Flux Ropes in the Jovian Magnetotail
Geophysical Research Letters, 2021 Two ion‐inertial scale magnetic flux ropes are identified in the Juno magnetic field measurements in the dawnside Jovian magnetotail. Previously reported plasmoids in this region had typical diameters of several Jovian radii (RJ).

Viscous Effects on Nonlinear Double Tearing Mode and Plasmoid Formation in Adjacent Harris Sheets
Magnetochemistry, 2023 In this paper, we study the effects of viscosity on the evolution of the double tearing mode (DTM) in a pair of adjacent Harris sheets based on the resistive MHD model in the NIMROD code.

Model of Hall Reconnection [PDF]
Physical Review Letters, 2008 The rate of quasi-stationary, two-dimensional magnetic reconnection is calculated in the framework of incompressible Hall magnetohydrodynamics (MHD). The calculation is based on the solution of Hall-MHD equations that include Hall and electron pressure terms for electric current.

Electron Signatures of Reconnection in a Global eVlasiator Simulation
Geophysical Research Letters, 2022 Geospace plasma simulations have progressed toward more realistic descriptions of the solar wind–magnetosphere interaction from magnetohydrodynamic to hybrid ion‐kinetic, such as the state‐of‐the‐art Vlasiator model.

Emission Mechanisms of Fast Radio Bursts
Universe, 2021 Fast radio bursts (FRBs) are recently discovered mysterious single pulses of radio emission, mostly coming from cosmological distances (∼1 Gpc). Their short duration, ∼1 ms, and large luminosity demonstrate coherent emission.

On the location of dayside magnetic reconnection during an interval of duskward oriented IMF [PDF]
, 2007 We present space- and ground-based observations of the signatures of magnetic reconnection during an interval of duskward-oriented interplanetary magnetic field on 25 March 2004.
