LHAASO-WCDA observed a 5 days TeV-delayed flaring event in blazar 1ES 1959+650
Zhen Cao, F. Aharonian, Y. X. Bai +339
We report a day-scale hard lag between GeV and TeV -ray emission from the HBL 1ES~1959+650 in early 2024. Since the LHAASO-WCDA real-time monitoring system began operation in la…
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 Comparative Study of TeV Gamma-Ray Sources with Various Objects
Xin Zhou, Ji Yang, Yang Su +5
We investigate the relationships between LHAASO TeV gamma-ray sources and various kinds of objects, including pulsar wind nebulae (PWNe), supernova remnants (SNRs), HII regions, mi…
Modeling the Saddle-like GeV-TeV Spectrum of HESS J1809-193: -Rays Arising from Reverse-Shocked Pulsar Wind Nebula?
Jiaxu Sun, Yang Chen, Yiwei Bao +2
Evolution of pulsar wind nebulae (PWNe) could be expected to leave imprints in -rays. We suggest that intriguing GeV-TeV spectral energy distribution (SED) of HESS J1809193 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…
Mirages and Large TeV Halo-Pulsar Offsets from Cosmic Ray Propagation
Yiwei Bao, Gwenael Giacinti, Ruo-Yu Liu +2
The study of extended -ray sources usually assumes symmetric diffusion of cosmic rays. However, recent observations of multiple sources near single pulsars and significant offse…
