Kinetic Simulations of Particle Acceleration in Relativistic Perpendicular Electron-positron Shocks with Proton Admixture
Huan Yu, Qi Xia, Jun Fang
Particle acceleration in relativistic shocks of electron-positron plasmas with proton admixture is investigated through two-dimensional (2D) particle-in-cell (PIC) simulations. The…
Particle Acceleration along Magnetic Fields as the Origin of Ear-like Structures in Supernova Remnants
Huan Yu, Jun Fang
The origin of ear-like structures with two opposite lobes extending from the shell of supernova remnants (SNRs) remains a subject of active debate, with proposed mechanisms ranging…
Nonthermal Acceleration of Electrons, Positrons and Protons at a Nonrelativistic Quasiparallel Collisionless Shock
Huan Yu, Qi Xia, Jun Fang
Energetic positrons have been observed in the interstellar medium, and high-energy positrons with relativistic energies up to approximately 1 TeV have been detected in Galactic cos…
Kinetic Simulation on Electron, Proton and Helium Acceleration in a Nonrelativistic Quasiparallel shock
Jun Fang, Qi Xia, Shiting Tian +2
In addition to electrons and protons, nonrelativistic quasiparallel shocks are expected to possess the ability to accelerate heavy ions. The shocks in supernova remnants are genera…
Investigating the energy distribution of the high-energy particles in the Crab nebula
Lu Wen, Ke-Yao Wu, Huan Yu +1
The Crab nebula is a prominent pulsar wind nebula (PWN) detected in multiband observations ranging from radio to very high-energy (VHE) -rays. Recently, -rays with energies a…

Jing-Wen Yan, Chun-Yan Lu, Lu Wen +2
G349.7 + 00.2 is a young Galactic supernova remnant (SNR) with a mushroom morphology in radio and X-rays, and it has been detected across the entire electromagnetic spectrum from r…
Numerically investigating the morphology of the supernova remnant SN 1006 in the ambient medium with a density discontinuity
Jun Fang, Jingwen Yan, Lu Wen +2
Multiband observations on the type Ia supernova remnant SN 1006 indicate peculiar properties in its morphologies of emission in the radio, optical and X-ray bands. In the hard X-ra…
Early acceleration of electrons and protons at the nonrelativistic quasiparallel shocks with different obliquity angles
Jun Fang, Chun-Yan Lu, Jing-Wen Yan +1
The early acceleration of protons and electrons in the nonrelativistic collisionless shocks with three obliquities are investigated through 1D particle-in-cell simulations. In the…
An explanation for the peculiar periphery of supernova remnant G309.2-0.6
Huan Yu, Jun Fang
Supernova remnant (SNR) G309.2-0.6 has a peculiar radio morphology with two bright ears to the southwest and northeast, although the main shell outside the ears is roughly circular…
An explanation of the formation of the peculiar periphery of Tycho's supernova remnant
Jun Fang, Huan Yu, Li Zhang
Tycho's supernova remnant (SNR) has a periphery which clearly deviates from spherical shape bash on the X-ray and radio observations. The forward shock from the southeast to the no…
