In simulations and laboratory experiments, they have demonstrated robustness to real-world effects such as photon and detector noise, misregistration, vibrations, and rapid variations in seeing conditions. However, their performance has not yet been validated on sky. We report the first on-sky demonstration of a reinforcement learning controller for adaptive optics, named Policy Optimization for AO (PO4AO). We further analyze its on-sky behavior and identify directions f","authors_text":"Angelie Alagao, Benoit Neichel, Byron Engler, Jalo Nousiainen, Jean-Francois Sauvage, Jonathan Dray, Markus Kasper, Romain Fetick, Sylvain Cetre, Vincent Chambouleyron","cross_cats":["cs.LG","cs.RO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-06-09T12:26:06Z","title":"On-sky demonstration of reinforcement learning for adaptive optics control"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.10771","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":"sha256:064ec1120713c381cd58db10af9b36766513bfd5e931bb74ebcb6e9da9e10979","target":"record","created_at":"2026-06-10T01:10:39Z","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":"96637cf021aa83b294bdd2997de4270857424715f58593403a62d9e1ffa6ca73","cross_cats_sorted":["cs.LG","cs.RO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-06-09T12:26:06Z","title_canon_sha256":"4d38c6ae6ef01304217f2459f66370346929e6d26a7e4bd5e52f8e900517a5ec"},"schema_version":"1.0","source":{"id":"2606.10771","kind":"arxiv","version":1}},"canonical_sha256":"ab15a3eaed05f8a705edea855dba9b17d664af8cfad52d6901c35e6a21188377","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ab15a3eaed05f8a705edea855dba9b17d664af8cfad52d6901c35e6a21188377","first_computed_at":"2026-06-10T01:10:39.761388Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-10T01:10:39.761388Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DlFADBMuywSFPxauZQzvFFZHsa5vV6Y41G0FoXmMDGGIbM2P3lqiOWAucAK+AymhdqiT2AXd4yC/qL8X+IpFAg==","signature_status":"signed_v1","signed_at":"2026-06-10T01:10:39.762047Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.10771","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:064ec1120713c381cd58db10af9b36766513bfd5e931bb74ebcb6e9da9e10979","sha256:732a958f63c00305e7e24e3da0b6b6a606a2cc0a512c83ad0f436128ae5d845a"],"state_sha256":"1bff5af688bce99a8cf5b0b6d614a9113ac7a87a089991b45625cd272bff3f12"}
