Detection of two TeV gamma-ray outbursts from NGC 1275 by LHAASO

Zhen Cao, F. Aharonian, Axikegu +275

The Water Cherenkov Detector Array (WCDA) is one of the components of Large High Altitude Air Shower Observatory (LHAASO) and can monitor any sources over two-thirds of the sky for…

LHAASO detection of very-high-energy gamma-ray emission surrounding PSR J0248+6021

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

We report the detection of an extended very-high-energy (VHE) gamma-ray source coincident with the location of middle-aged (62.4~\rm kyr) pulsar PSR J0248+6021, by using the LHAASO…

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…

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…

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…

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 observation of the Crab Nebula with LHAASO-KM2A for the performance study

F. Aharonian, Q. An, Axikegu +246

As a sub-array of the Large High Altitude Air Shower Observatory (LHAASO), KM2A is mainly designed to cover a large fraction of the northern sky to hunt for gamma-ray sources at en…
