The absence of such a signal in coincidence with SN 1987A neutrinos, using the coherent Milky Way field, provides well-studied constraints on $g_{ap}\\times g_{a\\gamma}$ (axion-proton times axion-photon couplings) and on $g_{a\\gamma}$ alone. We show that the small-scale power of the turbulent magnetic field component boosts axion-photon conversion and, crucially, extends sensitivity to larger masses. The turbulent field components of the Milky Way and of the Large Magellanic Cloud (hosting SN 1987A) yield improve"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The turbulent field components of the Milky Way and of the Large Magellanic Cloud yield improvements of up to two orders of magnitude in g_ap × g_aγ.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The assumed spectrum and coherence properties of the turbulent magnetic field components are accurate for the relevant propagation distances and axion mass range.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Turbulent magnetic fields enhance axion-photon conversion signals from supernovae, improving limits on axion-proton and axion-photon couplings by up to two orders of magnitude.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Turbulent magnetic fields boost axion-to-gamma conversion from supernovae by up to two orders of magnitude.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"e5a83e9357f3eac6951b44cfdc5ad60635bfcb28cccd01701200eb957812ab8a"},"source":{"id":"2605.15261","kind":"arxiv","version":1},"verdict":{"id":"05e77a38-c070-4e7f-a892-f77b2ceab3ee","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T16:06:46.311147Z","strongest_claim":"The turbulent field components of the Milky Way and of the Large Magellanic Cloud yield improvements of up to two orders of magnitude in g_ap × g_aγ.","one_line_summary":"Turbulent magnetic fields enhance axion-photon conversion signals from supernovae, improving limits on axion-proton and axion-photon couplings by up to two orders of magnitude.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The assumed spectrum and coherence properties of the turbulent magnetic field components are accurate for the relevant propagation distances and axion mass range.","pith_extraction_headline":"Turbulent magnetic fields boost axion-to-gamma conversion from supernovae by up to two orders of magnitude."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2605.15261/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"doi_title_agreement","ran_at":"2026-05-19T16:31:18.408734Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-19T16:18:00.967166Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"claim_evidence","ran_at":"2026-05-19T14:41:54.270393Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"ai_meta_artifact","ran_at":"2026-05-19T13:33:22.807571Z","status":"skipped","version":"1.0.0","findings_count":0}],"snapshot_sha256":"512e6775a275394360a985d3f49d54c0b6516282a23307e0dd8f508dbe2e4c64"},"references":{"count":91,"sample":[{"doi":"","year":1977,"title":"R.
