Twisted-pair unilateral reconnection: A unifying driver for magnetically powered astrophysical bursts
Shu-Ping Yan, Wenhui Yu, Jing Ye +11
Magnetic reconnection in twisted loops has long been invoked as an engine powering energetic transients from black hole accretion to neutron star mergers, yet never directly observ…
A Method for Imaging Interplanetary Magnetic Field Strength and Orientation
Chuanpeng Hou, Huirong Yan, Siqi Zhao
Measurements of interplanetary magnetic fields have long relied on spacecraft measurements, which provide only in-situ sampling and therefore cannot capture the global magnetic str…
Pitch-Angle Scattering of Cosmic Rays: Confronting Theory with Observations
Huirong Yan, Siqi Zhao, Ming Zhang
Cosmic ray (CR) propagation is controlled by scattering in turbulent magnetic fields in space. In general, diffusive propagation is governed by pitch-angle diffusion in phase space…
Non-Markovian Cosmic-Ray Pitch-Angle Transport from Mirror Interactions
Kai Yan, Huirong Yan, Parth Pavaskar +2
Cosmic-ray pitch-angle transport in magnetohydrodynamic (MHD) turbulence is governed by the interplay between magnetic mirroring and gyroresonant scattering. We develop a guiding-c…
Spatiotemporal Properties of Compressible Magnetohydrodynamic Turbulence from Space Plasma
Siqi Zhao, Huirong Yan, Terry Z. Liu +2
Previous studies have established that a weak-to-strong transition occurs in Alfvenic magnetohydrodynamic (MHD) turbulence as energy cascades from large to small scales. However, t…
Compressible Turbulence as a Source of Particle Beams and Ion Bernstein Waves in Collisionless Plasmas
Chuanpeng Hou, Huirong Yan, Siqi Zhao
Unraveling the origin of proton beams and ion Bernstein waves is important to understanding kinetic dissipation in the solar wind. Here we focus on their generation mechanisms, rat…
