{"arxiv_id":"2608.17599","title":"SST-1M: Recent results and prospects for observation of the Galactic Center region","abstract":"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 Ond\\v{r}ejov 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.","primary_cat":"astro-ph.HE","cross_cats":["astro-ph.IM"],"submitted_at":"2026-08-18T10:06:11+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Simulations of 250 hours of SST-1M observations from a proposed Argentine site predict 2 to 4 sigma sensitivity to a spectral cutoff in the Galactic Center diffuse emission.","novelty_score":5.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":0,"_links":{"html":"https://pith.science/paper/2608.17599","verdict":"/api/v1/verdicts/2608.17599"}}
