Statistical measurements of dispersion measure fluctuations of FRBs
Siyao Xu, David H. Weinberg, Bing Zhang
Extragalactic Fast Radio Bursts (FRBs) have large dispersion measures (DMs) and are unique probes of intergalactic electron density fluctuations. By using the recently released Fir…
Shock acceleration with oblique and turbulent magnetic fields
Siyao Xu, Alex Lazarian
We investigate shock acceleration in a realistic astrophysical environment with density inhomogeneities. The turbulence induced by the interaction of the shock precursor with upstr…
Superdiffusion of Cosmic Rays in Compressible Magnetized Turbulence
Yue Hu, A. Lazarian, Siyao Xu
Owing to the complexity of turbulent magnetic fields, modeling the diffusion of cosmic rays is challenging. Based on the current understanding of anisotropic magnetohydrodynamic (M…
Diffusion of cosmic rays in MHD turbulence
Siyao Xu
We review some recent findings on diffusion of cosmic rays (CRs) in magnetohydrodynamic (MHD) turbulence obtained by adopting the numerically-tested model of MHD turbulence, includ…
Mirror diffusion of cosmic rays in highly compressible turbulence near supernova remnants
Siyao Xu
Recent gamma-ray observations reveal inhomogeneous diffusion of cosmic rays (CRs) in the interstellar medium (ISM). This is expected as the diffusion of CRs depends on the properti…
Small-scale turbulent dynamo in astrophysical environments: nonlinear dynamo and dynamo in a partially ionized plasma
Siyao Xu, Alex Lazarian
Small-scale turbulent dynamo is responsible for the amplification of magnetic fields on scales smaller than the driving scale of turbulence in diverse astrophysical media. Most ear…
Diffusion of cosmic rays in MHD turbulence with magnetic mirrors
Alex Lazarian, Siyao Xu
As the fundamental physical process with many astrophysical implications, the diffusion of cosmic rays (CRs) is determined by their interaction with magnetohydrodynamic (MHD) turbu…
Anisotropic Turbulence in Position-Position-Velocity Space: Probing Three-Dimensional Magnetic Fields
Yue Hu, A. Lazarian, Siyao Xu
Direct measurements of three-dimensional magnetic fields in the interstellar medium (ISM) are not achievable. However, the anisotropic nature of magnetohydrodynamic (MHD) turbulenc…
Polarization Predictions in the GRB Prompt Phase with the Internal Shock Model
Mi-Xiang Lan, Hao-Bing Wang, Siyao Xu +2
As the standard gamma-ray burst (GRB) prompt-emission model, the internal shock (IS) model can reproduce the fast-rise and slow-decay features of the pulses in the GRB light curve.…
Measuring magnetization with rotation measures and velocity centroids in supersonic MHD turbulence
Siyao Xu, Yue Hu
The interstellar turbulence is magnetized and thus anisotropic. The anisotropy of turbulent magnetic fields and velocities is imprinted in the related observables, rotation measure…
Measuring Turbulence with Young Stars in the Orion Complex
Trung Ha, Yuan Li, Siyao Xu +2
Stars form in molecular clouds in the interstellar medium (ISM) with a turbulent kinematic state. Newborn stars therefore should retain the turbulent kinematics of their natal clou…
