We suppose that this emission is generated by accretion processes onto the central supermassive blackhole when an unbounded part of captured stars obtains an additional momentum. As a result a flux of subrelativistic protons is generated near the Galactic center which heats the background plasma up to temperatures about 6-10 keV and produces by inverse bremsstrahlung a flux of non-thermal X-ray emission in the energy range above 10 keV.","authors_text":"Aya Bamba, Chung-Ming Ko, Dmitrii Chernyshov, Dmitrii Prokhorov, Hajime Inoue, Kazuhiro Nakazawa, Kazuhisa Mitsuda, Kwong-Sang Cheng, Motohide Kokubun, Noriko Y.Yamasaki, Takayuki Yuasa, Vladimir Dogiel, Yoshitomo Maeda","cross_cats":["astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2009-06-12T02:56:39Z","title":"Origin of Thermal and Non-Thermal Hard X-ray Emission from the Galactic Center"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0906.2247","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f0d179eb0ae479c4a11fe41c77ba9d82e3dae67fe203b480af588c4458507b69","target":"record","created_at":"2026-05-18T02:13:20Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"422baad320898c55c5463915238f37edb74c104c50df6952d88f4166fa3b12e8","cross_cats_sorted":["astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2009-06-12T02:56:39Z","title_canon_sha256":"c97ddb9c66d150284944e55a3a6d4689a084ae6a06f06ac7bcf32b52ef7ddb22"},"schema_version":"1.0","source":{"id":"0906.2247","kind":"arxiv","version":1}},"canonical_sha256":"d01d036aae078991c0198413a57a2e5cbf73f07785754144c1d4011db7c33831","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d01d036aae078991c0198413a57a2e5cbf73f07785754144c1d4011db7c33831","first_computed_at":"2026-05-18T02:13:20.608781Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:13:20.608781Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tkbQBynjvWwUKZNQVjJT1XkVpea14IUo4rqK+njHP2Y9G0gePD/f6RENOZNAR4FoHCl8l25zdDXFwKr0lOnyDg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:13:20.609360Z","signed_message":"canonical_sha256_bytes"},"source_id":"0906.2247","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f0d179eb0ae479c4a11fe41c77ba9d82e3dae67fe203b480af588c4458507b69","sha256:e6dc261f43b9cf7fd95c0b585d82e05470313ca38b073b5fa318128e26c3fdcc"],"state_sha256":"431c11ec6964dcd77629a09d015e9d7c550e6db42fb42b20a7ffca9986d6de11"}
