Gamma-Ray Emission from the Crab Pulsar: A 17-Year Fermi-LAT Reanalysis
Liancheng Zhou, Yun-Lu Gong, Jun Fang +1
We present a reanalysis of 17 years of Fermi Large Area Telescope (LAT) observations of the Crab pulsar obtained between 2008 August and 2025 August. Using monthly Jodrell Bank rad…
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…
Detection of the Extended -ray Emission around TeV source 1LHAASO J0249+6022 with Fermi-LAT
Gong Yunlu, Zhou Liancheng, Xia Qi +3
1LHAASO J0249+6022 is an extended very-high-energy gamma-ray source discovered by the Large High-Altitude Air Shower Observatory. Based on nearly 16.1 years of data from the Fermi…
Multiband Nonthermal Radiative Properties of the Pulsar Wind Nebula CTB 87
Gong Yunlu, Zhou Liancheng, Xia Qi +3
The pulsar wind nebula CTB 87 (G74.9+1.2) is one of the sources emitting -rays with energies higher than 10 TeV, as measured by the Very Energetic Radiation Imaging Telescope Ar…
Likely detection of GeV γ-ray emission from pulsar wind nebula G32.64+0.53 with Fermi-LAT
Yifan Xiao, Keyao Wu, Jun Fang
In this study, we report the likely GeV γ-ray emissions originating from the pulsar PSR J1849-0001's pulsar wind nebula (PWN) G32.64+0.53. Our analysis covers approximately 14.7 ye…
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…
Possible GeV gamma-ray emission from the pulsar wind nebula in CTA 1
Liancheng Zhou, Keyao Wu, Yunlu Gong +1
We report a detection of GeV -ray emission potentially originating from the pulsar wind nebula in CTA 1 by analyzing about 15 yr of Fermi Large Area Telescope data. By selecting…
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…
A Revisit of the Two-Pole Caustic Model for GeV Light Curves of Gamma-Ray Pulsars
J. Fang, L. Zhang
The GeV light curve of a pulsar is an important probe to detect acceleration regions in its magnetosphere. Motivated by the recent reports on the observations of pulsars by {\it Fe…
