In analysis of archival survey data, we have discovered a 30-Jy dispersed burst of duration <5 ms located three degrees from the Small Magellanic Cloud. The burst properties argue against a physical association with our Galaxy or the Small Magellanic Cloud. Current models for the free electron content in the Universe imply a distance to the burst of <1 Gpc No further bursts are seen in 90-hr of additional observations, implying that it was a singular event such as a supernova or coalescence of relativistic objects. Hundreds of similar events could occur every day and act as insightful cosmological probes.","external_url":"https://arxiv.org/abs/0709.4301","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-23T22:38:32.029133+00:00","pith_arxiv_id":"0709.4301","created_at":"2026-05-09T06:00:35.620661+00:00","updated_at":"2026-05-23T22:38:32.029133+00:00","title_quality_ok":true,"display_title":"Lorimer, M","render_title":"Lorimer, M"},"hub":{"state":{"work_id":"a75d14b0-e704-49e8-afe5-abb95d60773e","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":11,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2024-08-09T05:48:05+00:00","last_pith_cited_at":"2026-05-03T17:48:16+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-05-26T00:06:08.625451+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":4},{"context_role":"dataset","n":1},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":4},{"context_polarity":"use_dataset","n":1},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
