A small scale structure model of jet based on the observation of microvariability
Jingran Xu, Shaoming Hu, Xu Chen +2
We developed a multi-region radiation model for the evolution of flux and spectral index with time. In this model, each perturbation component in the jet produces an independent fl…
Observation of gamma rays up to 320 TeV from the middle-aged TeV pulsar wind nebula HESS J1849000
M. Amenomori, S. Asano, Y. W. Bao +115
Gamma rays from HESS J1849000, a middle-aged TeV pulsar wind nebula (PWN), are observed by the Tibet air shower array and the muon detector array. The detection significance of…
Measurement of the Gamma-Ray Energy Spectrum beyond 100 TeV from the HESS J1843033 Region
M. Amenomori, S. Asano, Y. W. Bao +113
HESS J1843033 is a very-high-energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond $100\, {…
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…
Locations of optical and -ray emitting regions in the jet of PMN J2345-1555
Yun-Guo Jiang, Shao-Ming Hu, Xu Chen +2
We collect long term -ray, optical and radio GHz light curves of quasar object PMN J2345-1555. The correlation analyses between them are performed via the local cross-corre…
The ever-surprising blazar OJ 287: multi-wavelength study and appearance of a new component in X-rays
Pankaj Kushwaha, Alok C. Gupta, Paul J. Wiita +21
We present a multi-wavelength spectral and temporal investigation of OJ 287 emission during its strong optical-to-X-ray activity between July 2016 - July 2017. The daily -ray fl…
