We report on new very deep HST imaging that seems to be in tension with the SMBH runaway scenario but is consistent with the bulgeless edge-on galaxy scenario. The new observations were aimed at detecting two key features expected in the SMBH scenario, namely, the bow shock formed where the SMBH meets the surrounding medium, and a counter stellar wake created by another binary SMBH hypothesized as part of the ej","authors_text":"Ignacio Trujillo (IAC/ULL), Jorge S\\'anchez Almeida (IAC/ULL), Mireia Montes (IAC/ULL)","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-05-31T18:00:07Z","title":"Deep HST imaging favors the bulgeless edge-on galaxy explanation for the hypothetical stellar wake created by a runaway supermassive black hole"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2406.00102","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":"sha256:5f4b975fb31005c94515548dd4c5bc81896133296350a30fceb76439f43a278c","target":"record","created_at":"2026-07-05T08:25:56Z","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":"f42e795bf24d804f623cb43c0b888acfb08b257c151015b16df6b6dbf485e49c","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-05-31T18:00:07Z","title_canon_sha256":"74a752124c348f98c365cc29aa7f36166e44105673f6de8e0489bd2f8cf05895"},"schema_version":"1.0","source":{"id":"2406.00102","kind":"arxiv","version":1}},"canonical_sha256":"55f5be482cc806c9e844700019a5af7a55a34810250fa0ef01084b185e0e2cf2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"55f5be482cc806c9e844700019a5af7a55a34810250fa0ef01084b185e0e2cf2","first_computed_at":"2026-07-05T08:25:56.968692Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:25:56.968692Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nv3/92ZB5C8BffrmEioektzDuVzmTL6dzxif0AS+21djj71o6M28nWmZjZxOkSecKkfxpXZvm+waDZQPsTfLDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T08:25:56.969241Z","signed_message":"canonical_sha256_bytes"},"source_id":"2406.00102","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5f4b975fb31005c94515548dd4c5bc81896133296350a30fceb76439f43a278c","sha256:d571d2247d16bb00e21ce40230a05da1e3f9ba1ae423b97d888ea84bd7aacd74"],"state_sha256":"4b9e902a011ff2e53fe55836f3ec69249db3e0990f917cc132fdbc59e2229958"}
