银心是一个拥挤的区域，包含强大的粒子加速器和产生非热辐射的天体，其中包括被称为“脊”的弥散甚高能（VHE）伽马射线成分，其硬能谱表明粒子被加速至PeV能量。相关过程可通过切伦科夫望远镜观测进行检验，源参数也可借此得到约束。目前，两台单镜小型切伦科夫望远镜（SST-1M）正在翁德热约夫天文台以立体模式运行，其未来搬迁选址正在考虑中，其中包括一个对银心具有极佳观测视野的站点。本文展示了近期观测结果，证明SST-1M具备探测延展辐射的能力，并探讨了探测银心区域的前景，包括对10 TeV以上能谱截断的搜寻。研究表明，SST-1M拥有大视场和优良的VHE灵敏度，是搜寻PeVatrons的理想仪器。
英文摘要
The Galactic Center is a crowded region containing powerful particle accelerators and objects producing non-thermal radiation, including the diffuse very-high-energy (VHE) gamma-ray component known as the `Ridge', whose hard spectrum suggests particle acceleration up to PeV energies. The relevant processes can be tested, and the source parameters can be constrained via Cherenkov telescope observations. Two Single-Mirror Small-Size Cherenkov Telescopes (SST-1M) are currently operated in stereoscopic mode at the Ondřejov Observatory. Their future relocation is being considered, including a site with excellent visibility of the Galactic Center. We present recent observations demonstrating SST-1M capabilities for detecting extended emission and discuss prospects for probing the Galactic Center region, including searches for a spectral cut-off above 10 TeV. We show that the large field-of-view and good VHE sensitivity make SST-1M an ideal instrument for the search for PeVatrons.
