Assuming that the axion is the dark matter, we discuss the reach of a successful detection by a given experimental setup in a particular axion mass window for different modifications of the cosmological background before primordial nucleosynthesis occurred. Results are presented both in the case where the present energy budget in cold axions is produced through the vacuum realignment mecha","authors_text":"Luca Visinelli, Nicklas Ramberg","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2019-04-11T14:09:41Z","title":"Probing the Early Universe with Axion Physics and Gravitational Waves"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.05707","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:d3d23481fa022a2e05a226509adef9bce3482cc12a06db4eaa1365998fe9da19","target":"record","created_at":"2026-05-17T23:43:02Z","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":"6a46e49e7b4e1ace69e3ece87c036bb3f4bb8b9c997355847f254f7d2ee96a88","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2019-04-11T14:09:41Z","title_canon_sha256":"f36a8edd4a1a9bc137c288a3eb8ffeb06a12ec681eb8ebf585c80c007f068710"},"schema_version":"1.0","source":{"id":"1904.05707","kind":"arxiv","version":2}},"canonical_sha256":"6020fe9e97c01e5f77c98027ab3545e13b4afc56fbcdce22310c43f6cdb56325","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6020fe9e97c01e5f77c98027ab3545e13b4afc56fbcdce22310c43f6cdb56325","first_computed_at":"2026-05-17T23:43:02.598915Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:02.598915Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UegYS4AFtmCx1gXuuyDRlkU7xzt/trK8h/VOw484EKU4YW8iftehom4NjYKGYUWCcBOUuaXVnM+gsL3mNFsWAg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:02.599345Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.05707","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d3d23481fa022a2e05a226509adef9bce3482cc12a06db4eaa1365998fe9da19","sha256:eb67aef0335e0b07f82c57248416b5f8ab7bc84e7b7de9a2437015ff990a2031"],"state_sha256":"4cd8bea5518145b56ccca1a89c4887f0ac942bb58b50b2a0b57b701a35c27109"}
