摘要

Abstract

Gamma-ray astronomy is a critical tool for probing high-energy astrophysical processes. Among celestial sources, the Crab Nebula is a standard candle owing to its persistent and well-characterized gamma-ray emission. This work is devoted to the detection of gamma rays from the Crab Nebula by the TAIGA-IACT—imaging atmospheric Cherenkov telescopes in stereo mode in the period 2020–2023. During the analyzed period of observations, the installation included 2 and 3 telescopes at a distance of \({\sim}\) 320 m from each other. Each telescope has a reflector with a diameter of 4.3 m, in the focus of which is located a recording camera with a field of view of \(10^{\circ}\times 10^{\circ}\) . The energy threshold of the setup in the stereo mode of observations for gamma rays was \({\sim}\) 8 TeV. This work presents approach for reconstructing EAS parameters and gamma-hadron separation from stereoscopic TAIGA-IACT data. The energy spectrum of the PWN Crab Nebula is obtained.
