Constraints on Ultra Heavy Dark Matter Properties from Dwarf Spheroidal Galaxies with LHAASO Observations

Zhen Cao, F. Aharonian, Q. An +276

In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by da…

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…

Measurements of All-Particle Energy Spectrum and Mean Logarithmic Mass of Cosmic Rays from 0.3 to 30 PeV with LHAASO-KM2A

The LHAASO Collaboration, Zhen Cao, F. Aharonian +277

We present the measurements of all-particle energy spectrum and mean logarithmic mass of cosmic rays in the energy range of 0.3-30 PeV using data collected from LHAASO-KM2A between…

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…

Very high energy gamma-ray emission beyond 10 TeV from GRB 221009A

Zhen Cao, F. Aharonian, Q. An +276

The highest energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report for the first time the detection of gamma-rays…

Does or did the supernova remnant Cassiopeia A operate as a PeVatron?

Zhen Cao, F. Aharonian, Q. An +276

For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dom…
