The external sources encode the leaks of gravitational radiation at null infinity. The Ward identities of this theory are shown to reproduce those of the $2d$ celestial CFT after relating Carrollian to celestial operators. This suggests a new set of interplays between gravity in asymptotically flat spacetime, sourced conformal Carrollian field theory and celestial CFT.","external_url":"https://arxiv.org/abs/2202.04702","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T06:03:58.416425+00:00","pith_arxiv_id":"2202.04702","created_at":"2026-05-10T12:30:23.477842+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":true,"display_title":"Carrollian Perspective on Celestial Holography","render_title":"Carrollian Perspective on Celestial Holography"},"hub":{"state":{"work_id":"823a9d07-872d-4a84-90bc-958ff2592a63","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":23,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2023-11-17T14:59:43+00:00","last_pith_cited_at":"2026-05-14T18:00:01+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":"2026-06-19T19:57:48.414371+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":13}],"polarity_counts":[{"context_polarity":"background","n":13}],"runs":{},"summary":{},"graph":{},"authors":[]}}
