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 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…
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…
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…
Regions of suppressed diffusion around supernova remnants?
Yiwei Bao, Pasquale Blasi, Yang Chen
The recent discovery of the so-called TeV halos has attracted much attention. The morphology of the emission requires that the region is characterized by severe suppression of the…
PeVatron Candidate SNR G106.3+2.7 in a Low-density Cavity: a Multiwavelength Test
Yiwei Bao, Ruo-Yu Liu, Chong Ge +1
In this paper, we constrain the density of the interstellar medium (ISM) around the hadronic PeVatron candidate, supernova remnant (SNR) G106.3+2.7, based on X-ray and -ray obse…
Flux Variations of Cosmic Ray Air Showers Detected by LHAASO-KM2A During a Thunderstorm on 10 June 2021
LHAASO Collaboration, F. Aharonian, Q. An +268
The Large High Altitude Air Shower Observatory (LHAASO) has three sub-arrays, KM2A, WCDA and WFCTA. The flux variations of cosmic ray air showers were studied by analyzing the KM2A…
