sst1mpipe repository is now open to public

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...

Detection of enhanced very-high-energy gamma-ray emission from Markarian 421

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...
