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…
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…
