Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +339
Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…
A Boundary-Consistent Two-Zone Electron Kernel for Distant Pulsar Contributions to Positron Flux and Anisotropy
Yiwei Bao, Jie-Shuang Wang, Hao Zhou
We present a semi-analytical series solution for electron and positron propagation in a spherical two-zone diffusion model. The solution treats slow diffusion inside a near-source…
Ring Spacing from a Fourth-Order Radial Feedback Green Function in a Keplerian Accretion Disk
Yiwei Bao, Can Cui
ALMA observations of protoplanetary disks reveal ubiquitous concentric ring structures whose origin remains debated. We present an exactly solvable local model for ring spacing in…
Extreme PeV accelerator associated with GRS 1915+105
Zhen Cao, F. Aharonian, Y. X. Bai +322
Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissi…
On the Contribution of Local Sources to the Galactic Cosmic-Ray Spectrum: An Exact Series Solution for Two-Zone Diffusion
Zi-Hang Liu, Yiwei Bao, Ruo-Yu Liu
Measurements of cosmic-ray proton and helium spectra below the knee show deviations from simple power laws, including multi-TeV structures. A possible explanation is that one or a…
Mirage Sources and Large TeV Halo-Pulsar Offsets: Exploring the Parameter Space
Yiwei Bao, Ruo-Yu Liu, Gwenael Giacinti +2
We investigate the asymmetric propagation of 100 TeV electrons (whose radiation mainly concentrates on 20--30 TeV) in turbulent magnetic fields around pulsars, using GPU-accelerate…
