SS1-1M consortium, 18. 3. 2024 The sst1mpipe repository is used for processing and analyzing data from the SST-1M prototype. We are happy to inform, that the repository is now public, and therefore easily accesible to anyone inside or outside the SST-1M collaboration. It provides tools for low-level data analysis up to DL3, which can be further analyzed using standard tools such as gammapy. Most of the functions and classes are now documented. Currently, two SST-1M telescopes are installed in Ondrejov, Czech Republic, being operated in both mono and stereo observation modes. More about current status of the telescopes, early science and performance can be found in recent proceedings...
Bastien Lacave, CTAO Science Symposium, 15-18 April 2024 in Bologna Current status and recent results of the SST-1M telescopes were presented at the CTAO Science Symposium in Bologna. Bastien Lacave, member of the SST-1M consortium, presented poster to the general audience, emhasizing achievemts reached with the telescopes operation in stereo mode and future prospects for scientific observations.

Astronomical Institute of the Czech Academy of Sciences, 5. 4. 2024 Two Cherenkov telescopes are located at the Ondřejov observatory. What makes them unique? Cherenkov telescopes are capable of capturing high-energy gamma rays, which cannot be detected in any other way. The telescopes are operated by the Astronomical Institute of the Academy of Sciences of the Czech Republic, the Institute of Physics of the Academy of Sciences of the Czech Republic, the Palacký University in Olomouc, the Henryk Niewodniczański Institute of Nuclear Physics of the Polish Academy of Sciences, the University of Geneva and other institutions of the SST-1M consortium....
Thomas Tavernier (on behalf of SST-1M Consortium), 15. 3. 2024 We report a significant increase in gamma-ray flux from Markarian 421 above 2 TeV. This observation was conducted through stereo observations using the 2 SST-1M IACTs currently in commissioning at the Ondrejov Observatory. The observations extends from 13 March 2024 20:53 to 00:20 UTC resulting in a livetime of approximately 3.3 hours, during which a detection significance of 6.8 sigma was achieved with notable excess up to 7 TeV. The observed flux from Markarian 421 reached levels typically observed from the Crab Nebula, suggesting a substantial increase compared to our...
Thomas Tavernier (FZU, Prague, Czech Republic), TeVPa 2023 – Napoli, 12. 9. 2023 SST-1M is a single-mirror Small Size Telescope prototype developed by a consortium of institutes from Poland, Switzerland and the Czech Republic. The design of the SST-1M follows the Davies-Cotton design, with a 9.42m2 multi-segment mirror. With a wide field of view of 9 degrees, SST-1M is designed to detect gamma rays in the energy range between 1 and 300 TeV. The two SST-1Ms that have been built are equipped with the DigiCam camera, which features a fully digital readout and trigger system using 250 MHz ADC, and a compact...

Jakub Jurysek (on behalf of SST-1M Group), ICRC 2023, Nagoya, Japan, 26. 7. – 3. 8. 2023 The Single-Mirror Small-Sized Telescope, or SST-1M, was originally developed as a prototype of a small-sized telescope for CTA, designed to form an array for observations of gamma-ray-induced atmospheric showers for energies above 3 TeV. A pair of SST-1M telescopes is currently being commissioned at the Ondrejov Observatory in the Czech Republic, and the telescope capabilities for mono and stereo observations are being tested in better astronomical conditions. The final location for the telescopes will be decided based on these tests. In this contribution,...
[ Astronomický ústav AV ČR, 2022-02-18] Mirrors for the second SST-1M (Small-Sized Telescope) telescope with a primary mirror diameter of 4.3 meters designed for the detection of Cherenkov radiation are currently being installed at the Ondřej observatory. Energetic electromagnetic radiation, such as X-rays or gamma rays, does not pass through the atmosphere. When a gamma photon passes through the atmosphere (as well as when a charged particle with high energy passes), a shower of secondary particles and Cherenkov radiation is produced. These sensitive telescopes with high temporal resolution can detect this Cherenkov radiation from the atmospheric shower. The sources of...
Two unique Cerenkov telescopes (SST-1M) are installed at the Astronomical Institute of the CAS in Ondrejov. The telescopes are designed to study gamma rays with extremely high energy coming from sources in our Galaxy or in more distant places in the Universe. This is an international project involving scientists from the CAS, Palacký University in Olomouc and teams from Switzerland and Poland. The optical design of SST-1M is based on the Dawies-Cotton optical design. The 4 m diameter mirror of the telescope is divided into 18 segments and a fully digital camera composed of 1296 pixels, each with a sampling...
