Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and neutrinos from space with sensitivity over the full celestial sky. POEMMA will air fluorescence produced by extensive showers (EASs) UHECRs potentially UHE above 20 EeV. Additionally, has ability Cherenkov signal upward-moving EASs induced Earth-interacting tau PeV. spacecraft are quickly re-orientate follow up transient neutrino sources obtain...
The single-mirror small-size telescope (SST-1M) is one of the three proposed designs for telescopes (SSTs) Cherenkov Telescope Array (CTA) project. SST-1M will be equipped with a 4 m-diameter segmented reflector dish and an innovative fully digital camera based on silicon photo-multipliers. Since SST sub-array consist up to 70 telescopes, challenge not only build excellent performance, but also design them so that their components can commissioned, assembled tested by industry. In this paper...
The Cherenkov Telescope Array (CTA) is the next generation very high-energy gamma-ray observatory, with at least 10 times higher sensitivity than current instruments. CTA will comprise several tens of Imaging Atmospheric Telescopes (IACTs) operated in array-mode and divided into three size classes: large, medium small telescopes. total reflective surface could be up to 10,000 m<sup>2</sup> requiring unprecedented technological efforts. properties reflector directly influence telescope...
We present a discovery and observation of an extraordinarily bright prompt optical emission the GRB 060117 obtained by wide-field camera atop robotic telescope FRAM Pierre Auger Observatory from 2 to 10 minutes after GRB. found rapid average temporal flux decay alpha = -1.7 +- 0.1 peak brightness R 10.1 mag. Later observations other instruments set strong limit on radio transient fluxes, unveiling unexpectedly further decay. interpretation featuring relatively steep electron-distribution...
Many atmospheric and climatic criteria have to be taken into account for the selection of a suitable site next generation imaging air-shower Cherenkov telescopes, "Cherenkov Telescope Array" CTA. Such data are not available with sufficient precision, thus comparison proposed sites final decision based on comprehensive characterization is impossible. Identical cross-calibrated instruments been developed which allow precise between sites, cross-validation existing data, ground-validation...
The SST-1M is one of three prototype small-sized telescope designs proposed for the Cherenkov Telescope Array, and built by a consortium Polish Swiss institutions. will operate with DigiCam - an innovative, compact camera fully digital read-out trigger electronics. A high level integration be achieved massively deploying state-of-the-art multi-gigabit transmission channels, beginning from ADC flash converters, through internal data signals over backplanes cables, to camera's server link....
A FRAM (F/(Ph)otometric Robotic Atmospheric Monitor) telescope is a system of robotic mount, large-format CCD camera and fast telephoto lens that can be used for atmospheric monitoring at any site when information about the transparency required with high spatial or temporal resolution where continuous use laser-based methods this purpose would interfere other observations. The original has been operated Pierre Auger Observatory in Argentina more than decade, while three FRAMs are foreseen...
The Fluorescence detector Array of Single-pixel Telescopes is a proposed low-cost, large-area, next-generation experiment for the detection ultrahigh-energy cosmic rays via atmospheric fluorescence technique. design involves deployment several hundred large field-of-view telescopes on regular grid thousand square kilometers in ground area. This paper describes optical prototype telescope, as well its mechanical support structure.
The All Sky Camera (ASC) for CTA Site characterization is an automated optical instrument providing observation of the night sky conditions above future Cherenkov Telescope Array observatory. It provides basic condition analysis like cloud coverage, position, nightsky background in visible light wave range and raw photometry. result will serve further Monte Carlo design studies calculations. ASC additional auxiliary instruments (e.g. Ceilometer) provide input data smart scheduler during...

The idea of using stellar photometry for atmospheric monitoring optical experiments in highenergy astrophysics is seemingly straightforward, but reaching high precision the order 0.01 determination vertical aerosol depth (VAOD) has proven difficult. Wide-field over a large span altitudes allows fast VAOD independently absolute calibration system, while providing this as useful by-product. Using several years data taken by FRAM (F/(Ph)otometric Robotic Atmospheric Monitor) telescope at Pierre...
