The Extended Ultrahigh-energy Gamma-Ray Emission in the Vicinity of PSR J2238+5903
Zhen Cao, F. Aharonian, Y. X. Bai +324
We present a comprehensive analysis of the recently discovered TeV gamma-ray source, LHAASO J2238+5900. Based on data collected from the LHAASO, our fitting results suggest that th…
Energy-Dependent Shifts of Medium-Scale Anisotropies in Very-High-Energy Cosmic Rays Observed by LHAASO-KM2A
The LHAASO collabration, Zhen Cao, F. Aharonian +310
Small deviations from isotropy in the arrival directions of Galactic cosmic rays serve as a unique probe of the local magnetic environment. In this Letter, we report observations o…
Measurement of the cosmic ray nickel energy spectrum from 10 GeV/n to 2 TeV/n with the DAMPE
F. Alemanno, Q. An, P. Azzarello +144
Nickel, one of the most tightly bound nuclei alongside iron, is the most abundant heavy element beyond iron in cosmic rays. With DAMPE's excellent charge resolution and broad energ…
Cygnus X-3: A variable petaelectronvolt gamma-ray source
The LHAASO Collaboration, Zhen Cao, F. Aharonian +324
We report the discovery of variable -rays up to petaelectronvolt from Cygnus X-3, an iconic X-ray binary. The -ray signal was detected with a statistical significance of ap…
Observations of the Fermi bubbles and the Galactic center excess with the DArk Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +145
The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector that surveys the -ray sky above with a peak acceptance of $\sim 0.2~\rm…
First detection of ultra-high energy emission from gamma-ray binary LS I +61 303
Zhen Cao, F. Aharonian, Y. X. Bai +320
We report the first detection of gamma-ray emission up to ultra-high-energy (UHE; 100 TeV) emission from the prototypical gamma-ray binary system LS I +61 303 using data from th…
