LHAASO-KM2A detector simulation using Geant4
Zhen Cao, F. Aharonian, Q. An +275
KM2A is one of the main sub-arrays of LHAASO, working on gamma ray astronomy and cosmic ray physics at energies above 10 TeV. Detector simulation is the important foundation for es…
Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
Observation of gamma rays up to 320 TeV from the middle-aged TeV pulsar wind nebula HESS J1849000
M. Amenomori, S. Asano, Y. W. Bao +115
Gamma rays from HESS J1849000, a middle-aged TeV pulsar wind nebula (PWN), are observed by the Tibet air shower array and the muon detector array. The detection significance of…
Measurement of the Gamma-Ray Energy Spectrum beyond 100 TeV from the HESS J1843033 Region
M. Amenomori, S. Asano, Y. W. Bao +113
HESS J1843033 is a very-high-energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond $100\, {…
A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A
LHAASO Collaboration
Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…
The First LHAASO Catalog of Gamma-Ray Sources
Zhen Cao, F. Aharonian, Q. An +276
We present the first catalog of very-high energy and ultra-high energy gamma-ray sources detected by the Large High Altitude Air Shower Observatory (LHAASO). The catalog was compil…
Measurement of ultra-high-energy diffuse gamma-ray emission of the Galactic plane from 10 TeV to 1 PeV with LHAASO-KM2A
Zhen Cao, F. Aharonian, Q. An +276
The diffuse Galactic -ray emission, mainly produced via interactions between cosmic rays and the interstellar medium and/or radiation field, is a very important probe of the dis…
Potential PeVatron supernova remnant G106.3+2.7 seen in the highest-energy gamma rays
M. Amenomori, Y. W. Bao, X. J. Bi +92
Cosmic rays (protons and other atomic nuclei) are believed to gain energies of petaelectronvolts (PeV) and beyond at astrophysical particle accelerators called 'PeVatrons' inside o…
Gamma-ray Observation of the Cygnus Region in the 100 TeV Energy Region
M. Amenomori, Y. W. Bao, X. J. Bi +110
We report observations of gamma-ray emissions with energies in the 100 TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directi…
First Detection of sub-PeV Diffuse Gamma Rays from the Galactic Disk: Evidence for Ubiquitous Galactic Cosmic Rays beyond PeV Energies
M. Amenomori, Y. W. Bao, X. J. Bi +92
We report, for the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. Particularly, all gamma rays above 398…
Calibration of the Air Shower Energy Scale of the Water and Air Cherenkov Techniques in the LHAASO experiment
