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…
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…
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…
A Non-Spherical Model for the Solar Coronal Magnetic Field
Ziqi Wu, Jiansen He, Chuanpeng Hou +7
The coronal magnetic field plays a fundamental role in governing coronal activities, driving space-weather events, and shaping the heliosphere. Due to a lack of direct observations…
Discovery of a new -ray source LHAASO J0341+5258 with emission up to 200TeV
The LHAASO Collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a new unidentified extended -ray source in the Galactic plane named LHAASO J0341+5258 with a pre-trial significance of 8.2 standard deviations above…
