Time-dependent Evolution of Proton Spectra in Supernova Remnants and Their Contribution to Galactic Cosmic Rays
Jun-Yu Shen, Hou-Dun Zeng, Qiang Yuan
Recent -ray observations indicate that the proton spectra of supernova remnants (SNRs) are well described by broken power laws, with both the spectral break energy, $E_{\mathrm{…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes,…
The Formation Rate and Luminosity Function of Fast X-ray transients from Einstein probe
Yizhou Guo, Houdun Zeng, Junjie Wei +4
Following its launch on 2024 January 9, the Einstein Probe (EP) telescope has detected hundreds of fast X-ray transients (FXTs), yet their physical origins remain elusive. Understa…
Contribution of Globular Clusters to Diffuse Gamma-ray Emission from Galactic Plane
Jiayin He, Houdun Zeng, Yi Zhang +2
The diffuse Galactic -ray emission (DGE) provides a valuable probe for investigating the cosmic ray propagation and interactions within our Galactic environment. Recent observat…
Contribution of Unresolved Sources to Diffuse Gamma-Ray Emission from the Galactic Plane
Jiayin He, Houdun Zeng, Yi Zhang +3
The diffuse gamma-ray emission from the Milky Way serves as a crucial probe for understanding the propagation and interactions of cosmic rays within our galaxy. The Galactic diffus…
Evolution of High-energy Electron Distribution in Pulsar Wind Nebulae
Yi-Ming Liu, Hou-Dun Zeng, Yu-Liang Xin +2
In this paper, we analyze the spectral energy distributions (SEDs) of 17 powerful (with a spin-down luminosity greater than erg s) young (with an age less than 150…
Prospects for the detection of very-high-energy pulsars with LHAASO and SWGO
Quan Hu, Yi Zhang, Kaikai Duan +1
Pulsations from the Crab pulsar have been detected by the MAGIC telescopes at energies up to 1.5 TeV, and the pulsed emission from the Vela pulsar was detected by H.E.S.S., reachin…
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…
