Here we point out that this can not only be used to provide a method to determine the standard relation between halo mass and concentration, but also to use large samples of objects in order to place constraints on dark matter self-interactions that can be more robust than constraints derived from individual objects. We demonstrate our method by considering a sample of about 50 objects distributed across the w","authors_text":"Alexey Boyarsky, Anastasia Sokolenko, Kyrylo Bondarenko, Torsten Bringmann","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-12-18T19:00:02Z","title":"Constraining self-interacting dark matter with scaling laws of observed halo surface densities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.06602","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":"sha256:5465341d6f6782640ff2336db8491231d47f26f058bfbc602138cbc188e0d218","target":"record","created_at":"2026-05-18T00:17:08Z","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":"5ada57412e08ce4388902318b7ba913d69a5c04c73f70130a99c484a847bddd2","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-12-18T19:00:02Z","title_canon_sha256":"cebb5603cff829945abb1c77a7b67d8d5ec3a8c2a4a801d4d0f22e47e929349f"},"schema_version":"1.0","source":{"id":"1712.06602","kind":"arxiv","version":2}},"canonical_sha256":"4c11e8d9a122f2707e3c1a132d65022e655b21954495cea1e7af3492994e1ff7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4c11e8d9a122f2707e3c1a132d65022e655b21954495cea1e7af3492994e1ff7","first_computed_at":"2026-05-18T00:17:08.171355Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:08.171355Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m0PAHvj4YBZqIDAF5F/fgSu2jOomBI3xOsyzCtUAI8YX/CxeMCaGw/RtoPc3CBSdlyGpYPrKrrJjHbjQ/gCYCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:08.171971Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.06602","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5465341d6f6782640ff2336db8491231d47f26f058bfbc602138cbc188e0d218","sha256:8ea989524846e342e24eb7a87cacde08bc0d316ad594766495d79371af02e65d"],"state_sha256":"b56ccf131ce91262f604ecfbe688eb4118ff23804e31d4b9efad3e2428e4def3"}
