The SST-1M collaboration is proud to announce the publication of a new scientific article presenting the first gamma-ray observations of the Crab Nebula using the SST-1M stereoscopic system. The paper describes the performance of the two SST-1M telescopes during their commissioning and scientific observation phase between September 2023 and March 2024. The observations, conducted in both monoscopic and stereoscopic modes, provide key validation of the instrument’s expected performance through comparison with detailed Monte Carlo simulations. This study represents an important milestone for the SST-1M project, demonstrating the capabilities of our SiPM-based IACT system for multi-TeV gamma-ray astronomy. Read the full...

[ Laetitia Gibaud, PAiP-2025, 20-22 February 2025 in Warsaw ]Laetitia Gibaud, a member of the SST-1M consortium, recently presented the latest developments of the project at the PAiP-2025 conference in Warsaw, Poland. Her talk covered the telescope and camera design, along with preliminary results from the commissioning phase and data analysis.This event was a great opportunity to showcase the promising capabilities of the SST-1M mini-array for high-quality astronomical observations.

The SST-1M imaging atmospheric Cherenkov telescope for gamma-ray astrophysics We are pleased to announce the publication of a new scientific article detailing the design, prototyping, and validation of the SST-1M telescope. This Small-Sized Telescope is optimized for gamma-ray astrophysics at very high energies and features a cost-effective, lightweight, and robust design suited for harsh environments. The article highlights the innovative fully digitized camera system based on silicon photomultipliers (SiPMs) and presents the first promising results from the operational SST-1M stereo system at the Ondřejov Observatory in the Czech Republic.
