An Enigmatic PeVatron in an Area around H ii Region G35.6−0.5

Z. Cao, F Aharonian, Axikegu, Yuting Bai et autres

Abstract Identifying Galactic PeVatrons (PeV particle accelerators) from ultrahigh-energy (UHE, >100 TeV) γ-ray sources plays a crucial role in revealing the origin of Galactic cosmic rays. The UHE source 1LHAASO J1857+0203u is suggested to be associated with HESS J1858+020, which may be …

Detection of Very High-energy Gamma-Ray Emission from the Radio Galaxy M87 with LHAASO

Z. Cao, F Aharonian, Axikegu, Yuting Bai et autres

Abstract The nearby radio galaxy M87 is a very high-energy (VHE) gamma-ray emitter established by observations with ground-based gamma-ray detectors. Here we report the long-term monitoring of M87 from 2021 to 2024 with the Large High Altitude Air Shower Observatory (LHAASO). M87 …

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

Z. Cao, F Aharonian, D. Bastieri, Y.J Bi et autres

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-WCDA data of live 796 days and LHAASO-KM2A data of live 1216 days. A significant excess of …

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

Z. Cao, F Aharonian, Qi An, M Axikegu et autres

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 dark matter annihilation or decay from 16 dwarf spheroidal galaxies in the …

Lattice defects distribution of H+ implanted 4H-SiC investigated by deep-ultraviolet Raman spectroscopy

G.W Wang, Wenbo Luo, Dailei Zhu, Yuedong Wang et autres

The defects distribution of ion-implanted SiC is a key to understanding changes in the electronic, optical, and mechanical properties of SiC devices. However, accessing the defect distribution within the sample primarily relies on simulation, yet a number of factors remain unaccounted for …
