The gamma-rays exhibit a power-law energy spectrum with a spectral index of -2.2 +/- 0.09 +/- 0.15 and a flux above the 165 GeV threshold of (1.82 +/- 0.22) * 10^-7 m^-2 s^-1. The measured flux and spectrum differ substantially from recent results reported in particular by the CANGAROO collaboration.","primary_cat":"astro-ph","cross_cats":[],"submitted_at":"2004-08-09T08:30:27+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"ACCEPT","confidence":"MODERATE","one_line_summary":"H.E.S.S. detected a point-like very-high-energy gamma-ray source at the Galactic Centre with a hard power-law spectrum (index 2.2) and a flux of 1.8e-7 per m2 per s above 165 GeV, inconsistent with CANGAROO's steep spectrum.","novelty_score":7.0,"correctness_risk":"low","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":22,"_links":{"html":"https://pith.science/paper/astro-ph/0408145","verdict":"/api/v1/verdicts/astro-ph/0408145"}}
