Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants
Zhen Cao, F. Aharonian, Y. X. Bai +320
The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…
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…
Evidence of cosmic-ray acceleration up to sub-PeV energies in the supernova remnant IC 443
Zhen Cao, F. Aharonian, Y. X. Bai +309
Supernova remnants (SNRs) have been considered as the primary contributors to cosmic rays (CRs) in our Galaxy. However, the maximum energy of particles that can be accelerated by s…
Study of Ultra-High-Energy Gamma-Ray Source 1LHAASO J0056+6346u and Its Possible Origins
Zhen Cao, F. Aharonian, Y. X. Bai +322
We report a dedicated study of the newly discovered extended UHE -ray source 1LHAASO J0056+6346u. Analyzing 979 days of LHAASO-WCDA data and 1389 days of LHAASO-KM2A data, we o…
Observation of the -ray Emission from W43 with LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +322
In this paper, we report the detection of the very-high-energy (VHE, ) and ultra-high-energy (UHE, ) -ray emissions from t…
Precise measurements of the cosmic ray proton energy spectrum in the "knee'' region
The LHAASO Collaboration, Zhen Cao, F. Aharonian +310
We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower…
