For modeling the former, we consider GRB170817A-inspired set of parameters, while for the latter, we employ ejecta profiles from numerical-relativity simulations. We find that the kilonova afterglow sky map has a doughnut-like structure at early times that becomes more ring-like at late times. This is caused by the fact that the synchrotron emission from electrons following Maxwellian distribution function dominates the early, beamed, emission while emissions from electrons following power","authors_text":"Masaru Shibata, Tim Dietrich, Vsevolod Nedora","cross_cats":["astro-ph.IM","gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2023-02-24T19:00:06Z","title":"Synthetic radio images of structured GRB and kilonova afterglows"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2302.12850","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":"sha256:802f5de24dd912b6ce4170e9f4ac497d2429340f61e2dc7d17ed45a9cf357d45","target":"record","created_at":"2026-07-05T06:36:29Z","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":"a18048b13a10f974fba316094192f46f999dcee6fa2c653b8cf8be74643bbea3","cross_cats_sorted":["astro-ph.IM","gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2023-02-24T19:00:06Z","title_canon_sha256":"7338a8a7220ddba3ab56df8e56ef66be350ac7295c087eb0717a8baa6c7285bd"},"schema_version":"1.0","source":{"id":"2302.12850","kind":"arxiv","version":1}},"canonical_sha256":"a737bbe641150b791e136c3b8357cb3958c6e5d8a95c0a133a1e78b88f0081a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a737bbe641150b791e136c3b8357cb3958c6e5d8a95c0a133a1e78b88f0081a7","first_computed_at":"2026-07-05T06:36:29.994085Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:36:29.994085Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vfpgUhbyVh6TOR3o38bZoLIXoVGdCtJP6+zY38YgAOTbwDz+7Jzwn7xbiR3RQ1cgCc/97GDk34okVRIg8YeGAw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:36:29.994608Z","signed_message":"canonical_sha256_bytes"},"source_id":"2302.12850","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:802f5de24dd912b6ce4170e9f4ac497d2429340f61e2dc7d17ed45a9cf357d45","sha256:fa265243ea8207ac27b457320f74e3b961cf7fa3e32bb66027c1feeeb86e1582"],"state_sha256":"19eefc9008412e78d0943dfbac58703fae591948b2a602eb8424c9437c260e60"}
