In particular, we investigate the impact of gravitational wave (GW) emission by the magnetar central engine on its electromagnetic (EM) counterparts in the ULTRASAT band. Our results show that GW emission by the magnetar has only a minor effect on the SBO light-curve. However, we find that SN light-curves can carry a direct signature of GW emission, which becomes more evident at late times (> 20-30 days).~Our results demonstrate that future ULTRASAT observations will provide crucia","authors_text":"Dafne Guetta, Simone Dall'Osso","cross_cats":[],"headline":"","license":"http://creativecommons.org/publicdomain/zero/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2025-04-17T10:49:10Z","title":"Hunting for newborn magnetars: a multi-messenger approach"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.12834","kind":"arxiv","version":1},"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":"sha256:7465e9c5966678021ac120786d43549e29289fb94b4c26f5223a79ad3071e19e","target":"record","created_at":"2026-07-05T10:50:22Z","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":"fe1c057242a1b457ff3e22a87f1f555633c2d9c4e10a59f3aa2d4982a3bb263a","cross_cats_sorted":[],"license":"http://creativecommons.org/publicdomain/zero/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2025-04-17T10:49:10Z","title_canon_sha256":"1117b2b3221131c58077b0c399650ebcf8187d5f4f511b76e5dd864996c3ca4d"},"schema_version":"1.0","source":{"id":"2504.12834","kind":"arxiv","version":1}},"canonical_sha256":"bf0e44960bb561c182f9629920ed5c5da8a59b54771239ffd6feabeb54fb138b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bf0e44960bb561c182f9629920ed5c5da8a59b54771239ffd6feabeb54fb138b","first_computed_at":"2026-07-05T10:50:22.890663Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:50:22.890663Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UsX4lD+HBMbbB05U13OwXDr9Iv1GUhd2MkjLiZiUu0yLQz8WDP+qWbLXQ6ZwdIYZ8VxaI+Dj0ayyUo0zTI1+BA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:50:22.891138Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.12834","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7465e9c5966678021ac120786d43549e29289fb94b4c26f5223a79ad3071e19e","sha256:753152731f07582145a5f3c8e87ebb341d850db08a9e6d7719d9c8a3ac6f84fe"],"state_sha256":"245752871f73af43ed1bbbf53cfb9e3ce8b7c7722106bb6571780b0113541c10"}
