Extreme PeV accelerator associated with GRS 1915+105
Zhen Cao, F. Aharonian, Y. X. Bai +322
Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissio…
LHAASO Detection of Ultra-High-Energy Gamma-Ray Emission toward the Giant Molecular Clouds
Zhen Cao, F. Aharonian, Y. X. Bai +310
The -ray from Giant molecular clouds (GMCs) is regarded as the most ideal tool to perform in-situ measurement of cosmic ray (CR) density and spectra in our Galaxy. We report the…
Energy calibration of LHAASO-KM2A using the cosmic ray Moon shadow
Zhen Cao, F. Aharonian, Y. X. Bai +323
We present a precise measurement of the westward, rigidity-dependent shift of the Moon's shadow using three and a half years of cosmic-ray data collected by the Kilometer Square Ar…
All-sky search for individual Primordial Black Hole bursts with LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +311
Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…
Evidence for particle acceleration approaching PeV energies in the W51 complex
The LHAASO Collaboration, Zhen Cao, F. Aharonian +284
The -ray emission from the W51 complex is widely acknowledged to be attributed to the interaction between the cosmic rays (CRs) accelerated by the shock of supernova remnant (SN…
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 (…
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…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implyi…
Prospect of detecting TeV halos with LHAASO: in the framework of the anisotropic diffusion model
Kai Yan, Ruo-Yu Liu, S. Z. Chen +1
The particle diffusion coefficients of three TeV pulsar halos observed so far are inferred to be significantly smaller than the typical value of the interstellar medium (ISM). The…
Peta-electron volt gamma-ray emission from the Crab Nebula
The LHAASO Collaboration, Zhen Cao, F. Aharonian +269
The Crab pulsar and the surrounding nebula powered by the pulsar's rotational energy through the formation and termination of a relativistic electron-positron wind is a bright sour…
