Light curves and images of hot spots orbiting a black hole are affected by a number of special and general relativistic effects, and they can be potentially used to check whether the object is a Kerr black hole of general relativity. However, in a previous study we have shown that the relativistic features are usually subdominant with respect to the background noise and the model-dependent properties of the hot spot, and ev","authors_text":"Cosimo Bambi, Dan Liu, Zilong Li","cross_cats":["astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-11-10T05:26:02Z","title":"Testing a class of non-Kerr metrics with hot spots orbiting SgrA$^*$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1411.2329","kind":"arxiv","version":2},"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:a61fe2c09f4c742af11ce334a0e252d9df8a608be7918d17c031f772c8a4c74f","target":"record","created_at":"2026-05-18T02:29:24Z","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":"28b0af735b085509f89dc42e60a91cb704c115b4b43af3564584bfcec395f7a1","cross_cats_sorted":["astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-11-10T05:26:02Z","title_canon_sha256":"93bdb4ca02017e4a3fc5b498136770f4a99624cdbb04ea4864a3c152b765f4cd"},"schema_version":"1.0","source":{"id":"1411.2329","kind":"arxiv","version":2}},"canonical_sha256":"60b3b42d0628a58dee93e9e7e165d63f502d065785a5ae203a7a6315783ffbbb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"60b3b42d0628a58dee93e9e7e165d63f502d065785a5ae203a7a6315783ffbbb","first_computed_at":"2026-05-18T02:29:24.709582Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:29:24.709582Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lwybf7uwhVPO9ixyuzELHGzLRQQ5yPWMnrg9YMedmx3WED4lJzr6cWyFUOhxVsx4JF64vwPtREcdbVAyAtdwAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:29:24.709945Z","signed_message":"canonical_sha256_bytes"},"source_id":"1411.2329","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a61fe2c09f4c742af11ce334a0e252d9df8a608be7918d17c031f772c8a4c74f","sha256:e9af5155963af47483f9eda5313caac226e4e3d3b58e3aef5bfa511fb8710a99"],"state_sha256":"4378e31055ff05d674ce9fd71a95b3d67146cc8c6e65e21997bd28e828a67a5e"}
