In this work, we study parsec-scale interstellar dust clouds in the neutral ISM of the Milky Way using two different probes: dust depletion and dust extinction. We examine their relationship to investigate the distribution of metals and dust in the Solar neighbourhood, and how they are related to the Local Bubble. We use measurements of dust depletion for individual gas clouds along sight lines of sight towards bright O/B stars within 1.1 kpc of the Sun, derived fr"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We show that it is possible to use complementary information from dust depletion and dust extinction to build more detailed maps of ISM metal and dust distributions.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"We assume a correlation between dust depletion and dust extinction density, which we use to imply that the absorption components are spatially associated with the peaks in dust extinction density.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Dust depletion from UV spectra is associated with peaks in 3D extinction density maps to locate and chemically characterize local gas clouds at ~100 pc scales.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Dust depletion measurements from UV spectra can be matched to peaks in 3D extinction maps to locate individual gas clouds and map metals in the local Milky Way.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"b9f58c896643a6988ed70dc775236dc2bf7c33f34341f09d604d044d3a905596"},"source":{"id":"2604.24752","kind":"arxiv","version":2},"verdict":{"id":"ffb44fe3-0512-4f8e-b49d-b2785331914b","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-08T02:29:26.601451Z","strongest_claim":"We show that it is possible to use complementary information from dust depletion and dust extinction to build more detailed maps of ISM metal and dust distributions.","one_line_summary":"Dust depletion from UV spectra is associated with peaks in 3D extinction density maps to locate and chemically characterize local gas clouds at ~100 pc scales.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"We assume a correlation between dust depletion and dust extinction density, which we use to imply that the absorption components are spatially associated with the peaks in dust extinction density.","pith_extraction_headline":"Dust depletion measurements from UV spectra can be matched to peaks in 3D extinction maps to locate individual gas clouds and map metals in the local Milky Way."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.24752/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"ai_meta_artifact","ran_at":"2026-05-21T06:34:31.073234Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-19T21:44:41.676259Z","status":"completed","version":"1.0.0","findings_count":0}],"snapshot_sha256":"4aae9ece37d66c74a57e158949ca1f7d22a86f664694e7db368490d506e1f82f"},"references":{"count":35,"sample":[{"doi":"","year":2021,"title":"Bailer-Jones, C.
