Particle Injection Problem in Magnetic Reconnection and Turbulence
Fan Guo, Omar French, Qile Zhang +2
Magnetic reconnection and turbulence in magnetically-dominated environments have been proposed as important nonthermal particle acceleration mechanisms that generate high energy pa…
Constraints on Primordial Magnetic Fields from High Redshift Stellar Mass Density
Qile Zhang, Shang Li, Xiu-Hui Tan +1
Primordial magnetic fields (PMFs) play a pivotal role in influencing small-scale fluctuations within the primordial density field, thereby enhancing the matter power spectrum withi…
Plasma Dynamics and Nonthermal Particle Acceleration in 3D Nonrelativistic Magnetic Reconnection
Qile Zhang, Fan Guo, William Daughton +2
Understanding plasma dynamics and nonthermal particle acceleration in 3D magnetic reconnection has been a long-standing challenge. In this paper, we explore these problems by perfo…
Particle Injection and Nonthermal Particle Acceleration in Relativistic Magnetic Reconnection
Omar French, Fan Guo, Qile Zhang +1
Magnetic reconnection in the relativistic regime has been proposed as an important process for the efficient production of nonthermal particles and high-energy emissions. Using ful…
Multi-species Ion Acceleration in 3D Magnetic Reconnection with Hybrid-kinetic Simulations
Qile Zhang, Fan Guo, William Daughton +4
Magnetic reconnection drives multi-species particle acceleration broadly in space and astrophysics. We perform the first 3D hybrid simulations (fluid electrons, kinetic ions) that…
Comment on "Nonideal Fields Solve the Injection Problem in Relativistic Reconnection"
Fan Guo, Xiaocan Li, Omar French +7
Recently, Sironi (PRL, 128, 145102; S22) reported the correlation between particles accelerated into high energy and their crossings of regions with electric field larger than magn…

We propose a model for interpreting highly variable ion composition ratios in solar energetic particles (SEP) events recently observed by Parker Solar Probe (PSP) at a…
Slow Shock Formation Upstream of Reconnecting Current Sheets
Harry Arnold, James Drake, Marc Swisdak +3
The formation, development and impact of slow shocks in the upstream region of reconnecting current layers are explored. Slow shocks have been documented in the upstream region of…
Efficient Nonthermal Ion and Electron Acceleration Enabled by the Flux-Rope Kink Instability in 3D Nonrelativistic Magnetic Reconnection
Qile Zhang, Fan Guo, William Daughton +2
The relaxation of field-line tension during magnetic reconnection gives rise to a universal Fermi acceleration process involving the curvature drift of particles. However, the effi…
Magnetic Energy Release, Plasma Dynamics, and Particle Acceleration during Relativistic Turbulent Magnetic Reconnection
Fan Guo, Xiaocan Li, William Daughton +5
In strongly magnetized astrophysical plasma systems, magnetic reconnection is believed to be a primary process during which explosive energy release and particle acceleration occur…
