Calculating the integrated galactic stellar initial mass function (IGIMF) as a function of the SFR of a galaxy, it follows that galaxies which have or which formed with SFRs > 10 Msol yr^-1 would have a top-heavy IGIMF in excellent consistency with the observations. Consequently and in agreement with observations, elliptical galaxies would have higher M/L ratios as a result of the overabundance of stellar remnants compared to a stellar population","authors_text":"Alexandre Vazdekis (IAC/ULL), Carsten Weidner (IAC/ULL), Jan Pflamm-Altenburg (HISKP), Pavel Kroupa (HISKP)","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-09-25T20:00:01Z","title":"The galaxy-wide IMF of dwarf late-type to massive early-type galaxies"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.6634","kind":"arxiv","version":4},"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:a69b57c5190fe5dfdce27fe28f07d1d2e78c883697625286b2792641ee9f831f","target":"record","created_at":"2026-05-18T01:47:26Z","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":"5cadb0a0f3f18c0f5b0794c73eb93cb0d815503f4836b0dbb30898b84d9aa343","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-09-25T20:00:01Z","title_canon_sha256":"1d16e078f8f5aee5255c1eda2de10e7556b31cd83aa80e5aa074182ab8114253"},"schema_version":"1.0","source":{"id":"1309.6634","kind":"arxiv","version":4}},"canonical_sha256":"b6724a274287319acf3296560127d16b122b15f91afd9b375893dba6badf0acd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b6724a274287319acf3296560127d16b122b15f91afd9b375893dba6badf0acd","first_computed_at":"2026-05-18T01:47:26.608219Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:47:26.608219Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sIFe1ViRTOz9X6wu6RK8Fpd8mr3zLIYl8KK+FN2PitGGskjhdNxdOaexR1HNK8gTjRsYINiZMqrghQg/omC2Ag==","signature_status":"signed_v1","signed_at":"2026-05-18T01:47:26.608789Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.6634","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a69b57c5190fe5dfdce27fe28f07d1d2e78c883697625286b2792641ee9f831f","sha256:7ae55aa490b4830bd7cde06954f0632c97c003db13f0c70469fd3f6500a3e7cc"],"state_sha256":"ff20058aa20f422de640b5537c8bc43fc2040f5446ccd665f216f58e7cd9742a"}
