Descripción
The Cygnus region is one of the richest and most complex areas on the Galactic plane, known for its intense star formation and the presence of numerous very-high-energy gamma-ray sources. Among these sources, VER J2019+368 ranks as one of the brightest, exhibiting a hard spectrum and complex morphology that suggests the presence of powerful particle accelerators. First discovered by MILAGRO and later resolved by VERITAS, its origin remains unclear. The recent detection of photons above 25 TeV by LHAASO has renewed interest in VER J2019+368 as a potential PeVatron. Since April 2024, the Single-Mirror Small-Size Telescopes (SST-1M), installed in Ondřejov, Czech Republic, have been conducting a stereoscopic observing campaign focused on the Cygnus region, with particular attention to VER J2019+368. The SST-1M telescopes are designed to cover an energy range from a few TeV to several hundred TeV, featuring a wide 9° field of view and a compact Davies-Cotton optical design optimized for good off-axis performance, making them well suited for the study of hard, extended sources. In this contribution, we present preliminary results from our campaign, including morphological and spectroscopic analyses of VER J2019+368, and discuss possible scenarios for the origin and nature of its emission.
