The study is based on a large sample of ~22 000 well-defined star-forming galaxies selected from the Sloan Digital Sky Survey (SDSS). The reddening parameterized by color excess E(B-V) is derived from the Balmer decrement. Besides the dependency of reddening on Halpha luminosity / surface brightness and gas phase metallicity, it is also correlated with the galaxy inclination,","authors_text":"Honglin Lu, Hongyan Zhou, Huiyuan Wang, Tinggui Wang, Ting Xiao, Xiaobo Dong (USTC)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-12-01T01:48:05Z","title":"Dust reddening in star-forming galaxies"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1112.0063","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":"sha256:993c605023175b34d4f374d0514ce1074f962436b3e5dd83597cb8246518c41e","target":"record","created_at":"2026-05-18T04:00:28Z","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":"fcbdbe03251ee1dc3b1d02e43cc1cc2d1caa242e5b21853531e07714d48a50a1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-12-01T01:48:05Z","title_canon_sha256":"a45c1bef6998d5775698ee98a261ee979e72f34a977ec3490bb9092aca52882b"},"schema_version":"1.0","source":{"id":"1112.0063","kind":"arxiv","version":2}},"canonical_sha256":"7f529175701daf58b94f778e5ea823f9ca2d91196727f5af9283db0f2339ba2e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f529175701daf58b94f778e5ea823f9ca2d91196727f5af9283db0f2339ba2e","first_computed_at":"2026-05-18T04:00:28.188940Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:00:28.188940Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tRcLC4jAqCxSbCSPE0qhFXQUuIyVuQv2owJKGDZ9xZuVlo9gHQONlpeRkrQ1duvdFQGKNnJtu6/tX9Gmaf8LAA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:00:28.189556Z","signed_message":"canonical_sha256_bytes"},"source_id":"1112.0063","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:993c605023175b34d4f374d0514ce1074f962436b3e5dd83597cb8246518c41e","sha256:7c1cb85455d71ef44cf99d5abd532f87c135c7f529c2a3b9a9e62091b1a35b5d"],"state_sha256":"f91c70abdc88e7e3068442769b3a434b150c2d8fa9cb3a9863e338fbfbd42cf8"}
