The origin of the knee in the all-particle energy spectrum is still unknown. One of the most important issues in cosmic ray physics is the measurement of the knee in the energy spectrum of individual components. LHAASO is made up of three detector arrays, which are the wide field-of-view Cherenkov telescope array (WFCTA), the kilometer square array (KM2A) and the water Cherenkov detector array...
We report on the measurement with high statistics of the energy spectrum of light component (Proton plus Helium nuclei) in cosmic rays by Large High Altitude Air Shower Observatory (LHAASO) around the knee region. LHAASO is a composite cosmic ray observatory, which consists of three detector arrays, including the square meter Kilometer Array (KM2A), the Water Cherenkov Detector Array (WCDA),...
Under Chinese-Russian cooperation, electron-neutron detector array (ENDA) makes progresses during the last half an year: ENDA has been extended from ENDA-16 to ENDA-64, covering area about 1000 m2. ENDA-64 is running smoothingly and sand cubes are being added into one cluster (16 detectors). In 2023, we got supports from both NSFC Major International Joint Research Project and NSFC General...
High-energy cosmic rays interact with the atmosphere, generating extensive air showers. Measuring the evolution of muon content in EAS is of profound significance for the research of interaction models. This report is based on the data samples recorded by LHAASO-KM2A of 2022 with zenith angle $\theta \leq 40^{\circ}$, which energy is estimated around $10^{\mathrm{14}} - 10^{\mathrm{16.7}} \,...
The temporal and spatial structure of an EAS front detected at ground level reflects the nature of the primary particle and its interactions with atmosphere nuclei. We give the experiment results of the temporal structure of the shower front of the electronic and muonic EAS components, observed to larger distances from the shower axis up to core distances of R = 500m at the maximum depth of...
The arrival time distribution of secondary particles from an extensive air shower is one of the important parameters to reconstruct the information of primary particles. Due to the acceleration/deceleration and deflection by the thunderstorm electric field, the number and space-time of the ground-level particles are altered, resulting in a variation of the shower detection and reconstruction....
Introduce the data transfer updates and status for KM2A/WCDA/WFCTA/GRB
This presentation will talk about the status of lhaaso computing platform in 2023.
In this presentation we report the very-high-energy (VHE) to ultra-high-energy (UHE) \gray emission detected by the Large High Altitude Air Shower Observation (LHAASO), from the direction toward the young star-forming region W43. The extended \gray source is detected with a significance of ${\sim}23\,\sigma$ with KM2A and a significance of ${\sim}27\,\sigma$ with WCDA. The angular extension of...
We analyze the LHAASO-KM2A data updated to 2023-07-31 and LHAASO-WCDA data updated to 2023-05 to study the morphological and spectral features of this source. Adopting the millimeter data from a multi-CO line survey towards LHAASO J1843-0338, we find a superbubble associated with the gamma-ray emission detected by LHAASO. Our further morphological and model studies on this source, suggest that...
