We used data from XMM-Newton and NuSTAR. We were able to well constrain the lag spectrum with respect to the softest (0.3--2.3 keV) band: the delay shows increasing lag values reaching a maximum delay of $\\sim$ 12 ms, between 6 and 6.4 keV. After this maximum, the value of the hard lag drops to 7 ms, followed by a recovery to a plateau at 9 ms for energies above 8 keV. NuSTAR data confirm this trend up to 30 keV, but the measurements are statistically poorer, and therefore, less ","authors_text":"Alessandro Riggio, Andrea Sanna, Antonino D'A\\`i, Fabio Pintore, Luciano Burderi, Rosario Iaria, Tiziana Di Salvo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2016-06-01T09:44:14Z","title":"Discovery of hard phase lags in the pulsed emission of GRO J1744-28"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.00194","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":"sha256:97446296cfff0d67a599424e1253229fd09e78bae2345ad14aca47bfa7d3d576","target":"record","created_at":"2026-05-18T00:59:58Z","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":"ada1a3fa3a256fa3a0df28f3c1880b899d608ea7c0577479047e37e1cb460c8f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2016-06-01T09:44:14Z","title_canon_sha256":"f8e9ca5189d330466b4b0c1497116692063a8971368311ca602c63403c3bb65a"},"schema_version":"1.0","source":{"id":"1606.00194","kind":"arxiv","version":2}},"canonical_sha256":"93bcb653fd6272a221614b1a8967c709d5e35dd28a5ec1e9ea98ae19c4f1d79a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"93bcb653fd6272a221614b1a8967c709d5e35dd28a5ec1e9ea98ae19c4f1d79a","first_computed_at":"2026-05-18T00:59:58.256904Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:59:58.256904Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"X0fdgIjkr+4igMEcSsuyLWcMGLeEARAuu5CWr0f9ZEwsBVOaknxTBf0IrsX/OpOgQa0NMCIgK3w4Xztew6ZNDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:59:58.257480Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.00194","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:97446296cfff0d67a599424e1253229fd09e78bae2345ad14aca47bfa7d3d576","sha256:1d81665f735f60d630523bcf74f2088caca339543bdd952963797fc87714d369"],"state_sha256":"c99424c9a3a85bdf96d4a01d53e2e2a5470e7f10a597c59a813683b230f978df"}
