Understanding this process is essential for uncovering the evolutionary connections between galaxies and cosmic structures. Here we study a sample of ten protoclusters at z~2-3 in different dynamical states that we estimate based on spectroscopic data of their members. We combine the dynamical information with HST imaging to measure galaxy sizes and pair fractions. Our analysis reveals a clear anti-correlation between the velocity dispersion of the protocluster and its galaxy p","authors_text":"Chao Yang, Dong Dong Shi, Haiguang Xu, Jia-Sheng Huang, Man Qiao, Qirong Yuan, Run Wen, Shuang Liu, Valentino Gonzalez, Xian Zhong Zheng, Xiaohu Yang, Yuheng Zhang, Zongfei Lyu","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-12-11T12:23:55Z","title":"A first measurement of galaxy merger rate increasing in dynamically colder protoclusters at cosmic noon"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.08336","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":"sha256:16cd6a13345491555e713ef14f91153e20fad2e7d46b9b8c528d8de2496239e1","target":"record","created_at":"2026-07-05T09:47:48Z","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":"a13688d93e5e38657b4d6d839aca0f2a6aa010407d32950a1ebed68be6f45eb6","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-12-11T12:23:55Z","title_canon_sha256":"ab591afb544657e9f7b594e7ac3f44d80737a2a2057a81ec298988fba7aafaa5"},"schema_version":"1.0","source":{"id":"2412.08336","kind":"arxiv","version":1}},"canonical_sha256":"3622409415920b32d5c93bdf1f4ef90bcd1c578b118577380b90ba025c77155a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3622409415920b32d5c93bdf1f4ef90bcd1c578b118577380b90ba025c77155a","first_computed_at":"2026-07-05T09:47:48.358827Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:47:48.358827Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tLFDkNCSpwgX9tMKs2gFXZ1Awe4pZo2Ipcr9dLXGAVZEoB/hWtfeujzLltGMMMT8SO6zbfehWozgiYt+T2NuAw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:47:48.359351Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.08336","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:16cd6a13345491555e713ef14f91153e20fad2e7d46b9b8c528d8de2496239e1","sha256:b0a89be3f9a05188dba920824997319f8fe5916f6c50233e298b2f2795626d59"],"state_sha256":"afee7145e8b4c8533dfa3dc1b1d4ad51f78e6ac0ceb25f3fdfd1d5d031b3e40c"}
