An Enigmatic PeVatron in an Area around HII Region G35.60.5
The LHAASO Collaboration, Zhen Cao, F. Aharonian +294
Identifying Galactic PeVatrons (PeV particle accelerators) from the ultra-high-energy (UHE, >100 TeV) -ray sources plays a crucial role in revealing the origin of Galactic cosm…
Data quality control system and long-term performance monitor of the LHAASO-KM2A
Zhen Cao, F. Aharonian, Axikegu +282
The KM2A is the largest sub-array of the Large High Altitude Air Shower Observatory (LHAASO). It consists of 5216 electromagnetic particle detectors (EDs) and 1188 muon detectors (…
Measurement of Very-high-energy Diffuse Gamma-ray Emissions from the Galactic Plane with LHAASO-WCDA
The LHAASO Collaboration, Zhen Cao, F. Aharonian +312
The diffuse Galactic gamma-ray emission is a very important tool used to study the propagation and interaction of cosmic rays in the Milky Way. In this work, we report the measurem…
Stringent Tests of Lorentz Invariance Violation from LHAASO Observations of GRB 221009A
The LHAASO Collaboration, Zhen Cao, F. Aharonian +283
On October 9, 2022, the Large High Altitude Air Shower Observatory (LHAASO) reported the observation of the very early TeV afterglow of the brightest-of-all-time GRB 221009A, recor…
Ultra-high-energy -ray emission associated with the tail of a bow-shock pulsar wind nebula
Zhen Cao, F. Aharonian, Y. X. Bai +292
In this study, we present a comprehensive analysis of an unidentified point-like ultra-high-energy (UHE) -ray source, designated as 1LHAASO J1740+0948u, situated in the vicinit…
Broadband -ray spectrum of supernova remnant Cassiopeia A
Zhen Cao, F. Aharonian, Y. X. Bai +311
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of 2.5 $\arcmin$. Although no extension…
