Abstract
The TAIGA astroparticle observatory is progressing with the
deployment of new detector stations. The Tunka-Grande —
scintillation counter array of the observatory expands with the new
...TAIGA-Muon stations. Several simulation studies were conducted for
optimisation of the new station positioning and
performance. Extensive air showers induced by gamma quanta or a
proton in the range from 100 TeV to 1 PeV at a zenith angle of 0°
were used for these studies. Based on the developed simulation, the
capabilities of identification of high energy extensive air showers
were studied. The soil thickness, the detector and station
positions, the lowest measurable energy range of the cosmic rays,
and different methods of air shower identification were
investigated.
This paper presents the results of an analysis of observations of the Crab Nebula gamma-ray source with the first two atmospheric Cherenkov telescopes of the TAIGA (Tunka Advanced Instrument for ...cosmic ray physics and Gamma Astronomy) astrophysical complex in the stereo mode of observations. The article analyzed observational data from 2020 to 2021. Over 36 hours of observations, a signal was obtained at a statistical significance level of 5
and a spectrum of gamma rays was plotted in the energy range from 2 to 70 TeV. The paper describes a technique for gamma–hadron separation and reconstruction of detected gamma-rays energy.
The corrected dependence of the mean depth of the EAS maximum \(X_{max}\) on the energy was obtained from the data of the Tunka-133 array for 7 years and the TAIGA-HiSCORE array for 2 years. The ...parameter \(\langle\ln A\rangle\), characterizing the mean mass compositon was derived from these results. The differential energy spectrum of primary cosmic rays in the energy range of \(2\cdot 10^{14}\) - \(2\cdot 10^{16}\)\,eV was reconstructed using the new parameter \(Q_{100}\) the Cherenkov light flux at the core distance 100 m.}

The Tunka Advanced Instrument for Gamma-ray and cosmic ray Astrophysics (TAIGA) is a hybrid experiment for the measurement of Extensive Air Showers (EAS) with good spectral resolution in the TeV to ...PeV energy range. In this domain, the long-sought Pevatrons can be detected. Currently the TAIGA detector complex combines a two wide angle shower front Cherenkov light sampling timing arrays (HiSCORE and Tunka-133), two 4 m class, 10
aperture Imaging Air Cherenkov Telescopes (IACTs) and 240 m
surface and underground charged particle detector stations. Our goal is to introduce a new hybrid reconstruction technique, combining the good angular and shower core resolution of HiSCORE with the gamma-hadron separation power of imaging air Cherenkov telescopes. This approach allows to maximize the effective area and simultaneously to reach a good gamma-hadron separation at low energies (few teraelectronvolts). At higher energies, muon detectors are planned to enhance gamma-hadron separation. During the commissioning phase of the first and second IACT, several sources were observed. First detections of known sources with the first telescope show the functionality of the TAIGA IACTs. Here, the status of the TAIGA experiment will be presented, along with first results from the current configuration.
The physical motivations, present status, main results in study of cosmic rays and in the field of gamma-ray astronomy as well future plans of the TAIGA-1 (Tunka Advanced Instrument for cosmic ray ...physics and Gamma Astronomy) project are presented. The TAIGA observatory addresses ground-based gamma-ray astronomy and astroparticle physics at energies from a few TeV to several PeV, as well as cosmic ray physics from 100 TeV to several EeV. The pilot TAIGA-1 complex is located in the Tunka valley, ~50 km west from the southern tip of the lake Baikal.
