“…Такой метод нашел практическое применение на телескопе ГТ-48 [11,12], где для наблюдений в различных диапазонах длин волн были использованы различные типы ФЭУ (оптические и УФ), а также позднее дополнительно изучался теоретически в связи с планированием новых черенковских гамма-телескопов [13,14]. На черенковском гамма-телескопе TAIGA-IACT [15] с модернизированной камерой на SiPM тот же метод может быть реализован с помощью специальных фильтров с полосой пропускания в диапазоне 300 nm, т. e., без применения двух различных типов SiPM. Это возможно потому, что эффективность детектирования некоторых типов SiPM в этом диапазоне все еще весьма значительна (5−20%).…”

We have modeled propagation of source signal and noise for a future camera of TAIGA-IACT Cherenkov gamma-ray telescope, which will be based on silicon photomultipliers sensitive in the 240 -- 600 nm range. It has been shown that employment of such detectors instead of traditional vacuum photomultipliers will allow one to decrease the energy threshold by a factor of about 2.5: from ~ 1.5 TeV down to ~ 0.6 TeV. We have also shown that application of a standard ultraviolet filter ZWB3 will decrease the source signal by a factor of 3, while the noise signal from the night sky will be decreased by a factor of 6. In this way the duty cycle of the telescope can be extended (the telescope will be able to operate during moonlit nights and during twilight) and the energy threshold further decreased down to ~ 0.3 TeV. A narrow 260 -- 300 nm filter can be employed to improve gamma-hadron separation of primary cosmic particles in the ~ 25 -- 50 TeV band.

“…There are currently five binary file formats used in the various TAIGA projects. They provide a representation of raw data obtained from five TAIGA sub-facilities: the gamma ray setups TAIGA-HiSCORE and TAIGA-IACT [31] and the cosmic ray setups Tunka-133 [38], Tunka-Rex [39], and Tunka-Grande [40]. The long-term preservation of raw binary data as originally generated is essential for re-running analysis and reproducing research results in the future.…”

Modern large-scale astroparticle setups measure high-energy particles, gamma rays, neutrinos, radio waves, and the recently discovered gravitational waves. Ongoing and future experiments are located worldwide. The data acquired have different formats, storage concepts, and publication policies. Such differences are a crucial point in the era of Big Data and of multi-messenger analysis in astroparticle physics. We propose an open science web platform called ASTROPARTICLE.ONLINE which enables us to publish, store, search, select, and analyze astroparticle data. In the first stage of the project, the following components of a full data life cycle concept are under development: describing, storing, and reusing astroparticle data; software to perform multi-messenger analysis using deep learning; and outreach for students, post-graduate students, and others who are interested in astroparticle physics. Here we describe the concepts of the web platform and the first obtained results, including the meta data structure for astroparticle data, data analysis by using convolution neural networks, description of the binary data, and the outreach platform for those interested in astroparticle physics. The KASCADE-Grande and TAIGA cosmic-ray experiments were chosen as pilot examples.

The Tunka Radio Extension (Tunka-Rex) is an antenna array spread over an area of about 1 km 2 . The array is placed at the Tunka Advanced Instrument for cosmic rays and Gamma Astronomy (TAIGA) and detects the radio emission of air showers in the band of 30 to 80 MHz. During the last years it was shown that a sparse array such as Tunka-Rex is capable of reconstructing the parameters of the primary particle as accurate as the modern instruments. Based on these results we continue developing our data analysis. Our next goal is the reconstruction of cosmic-ray energy spectrum observed only by a radio instrument. Taking a step towards it, we develop a model of aperture of our instrument and test it against hybrid TAIGA observations and Monte-Carlo simulations. In the present work we give an overview of the current status and results for the last five years of operation of Tunka-Rex and discuss prospects of the cosmic-ray energy estimation with sparse radio arrays. * now at the University of Zürich †also at Vrije Universiteit Brussel, Belgium
