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…
