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…
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…
Large-scale anisotropy of Galactic cosmic rays as a probe of local cosmic-ray propagation
Ai-feng Li, Qiang Yuan, Wei Liu +1
Recent studies have shown that the anisotropy is of great value to decipher cosmic rays' origin and propagation. We have built an unified scenario to describe the observations of t…
Geminga SNR: Possible candidate of local cosmic-ray factory
Bing Zhao, Wei Liu, Qiang Yuan +5
The precise measurements of energy spectra and anisotropy could help us uncover the local cosmic-ray accelerators. Our recent works have shown that spectral hardening above G…
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…
A preliminary study about gravitational wave radiation and cosmic heat death
Jianming Zhang, Qiyue Qian, Yiqing Guo +2
We study the role of gravitational waves (GW) in the heat death of the universe. Due to the GW emission, in a very long period, dynamical systems in the universe suffer from persis…
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…
