Constraining the position of the knee in the galactic cosmic ray spectrum with ultra-high-energy diffuse -rays
Pei-pei Zhang, Yi-qing Guo, Bing-qiang Qiao +1
The diffuse -ray emission was measured up to TeV by the Tibet-AS experiment recently. Assuming that it is produced by the hadronic interaction between cosmic ray nuclei…
Peta-electron volt gamma-ray emission from the Crab Nebula
The LHAASO Collaboration, Zhen Cao, F. Aharonian +269
The Crab pulsar and the surrounding nebula powered by the pulsar's rotational energy through the formation and termination of a relativistic electron-positron wind is a bright sour…
Statistically study the optimal local sources for cosmic ray nuclei and electron
Qing Luo, Bing-qiang Qiao, Wei Liu +2
The local sources, such as Geminga SNR, may play important role for the anomaly of proton, electron and anisotropy in the past works. In fact, there exists twelve SNRs around solar…
Ultrahigh-energy diffuse gamma-ray emission from cosmic-ray interactions with medium surrounding acceleration sources
Pei-pei Zhang, Bing-qiang Qiao, Qiang Yuan +2
The diffuse -ray spectrum at sub-PeV energy region has been measured for the first time by the Tibet-AS experiment. It will shed new light on the understanding of origin and…
Discovery of a new -ray source LHAASO J0341+5258 with emission up to 200TeV
The LHAASO Collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a new unidentified extended -ray source in the Galactic plane named LHAASO J0341+5258 with a pre-trial significance of 8.2 standard deviations above 2…
Exploring Lorentz Invariance Violation from Ultra-high-energy Gamma Rays Observed by LHAASO
Zhen Cao, F. Aharonian, Q. An +268
Recently the LHAASO Collaboration published the detection of 12 ultra-high-energy gamma-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detect…
Discovery of the Ultra-high energy gamma-ray source LHAASO J2108+5157
The LHAASO collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a UHE gamma-ray source, LHAASO J2108+5157, by analyzing the LHAASO-KM2A data of 308.33 live days. Significant excess of gamma-ray induced showers is obse…
Galactic cosmic ray propagation: sub-PeV diffuse gamma-ray and neutrino emission
Bing-Qiang Qiao, Wei Liu, Meng-Jie Zhao +2
The Tibet ASgamma experiment just reported their measurement of sub-PeV diffuse gamma ray emission from the Galactic disk, with the highest energy up to 957 TeV. These gamma-rays a…
Prospects for the detection of the prompt very-high-energy emission from -ray bursts with the High Altitude Detection of Astronomical Radiation experiment
Guang-Guang Xin, Yu-Hua Yao, Xiang-Li Qian +15
The observation of very-high-energy (VHE, ) -ray emission from -ray bursts (GRBs), especially in the prompt phase, will provide critical information for unde…
Constraining the cosmic ray propagation halo thickness using Fermi-LAT observations of high-latitude clouds
Yu-Hua Yao, Bing-Qiang Qiao, Wei Liu +5
As a basic characteristic of cosmic ray (CR) propagation, the diffusive halo can advance our understanding of many CR-related studies and indirect dark matter. The method to derive…
Constraining the Thickness of the Galactic Halo through Cosmic-Ray Anisotropy Using the Spatial-Dependent-Propagation Model
Bing-Qiang Qiao, Yu-Hua Yao, Wei Liu +4
The spatial-dependent-propagation (SDP) model with a nearby source works well to reproduce the coevolving features of both cosmic-ray (CR)-nuclei spectra and anisotropy. However, i…
Performance of LHAASO-WCDA and Observation of Crab Nebula as a Standard Candle
LHAASO collaboration
The first Water Cherenkov detector of the LHAASO experiment (WCDA-1) has been operating since April, 2019. The first 10 months of data have been analyzed to test its performance by…
Possible bump structure of cosmic ray electrons unveiled by AMS-02 data and its common origin along with the nuclei and positron
Pei-pei Zhang, Bing-qiang Qiao, Wei Liu +3
The local pulsar and its progenitor, SNR, can together accelerate the positron, electron and nuclei to very high energy. The famous excesses of positron(nuclei) above () G…
