A. Konoplya, A. Zhidenko","year":2024,"venue":"gr-qc","abstract":"Quasinormal modes and grey-body factors are spectral characteristics corresponding to different boundary conditions: the former imply purely outgoing waves to the event horizon and infinity, while the latter allow for an incoming wave from the horizon, thus describing a scattering problem. Nevertheless, we show that there is a link between these two characteristics. We establish an approximate correspondence between the quasinormal modes and grey-body factors, which becomes exact in the high-frequency (eikonal) regime. We show that, in the eikonal regime, the grey-body factors of spherically symmetric black holes can be remarkably simply expressed via the fundamental quasinormal mode, while at smaller $\\ell$, the correction terms include values of the overtones. This might be interesting in the context of the recently observed connection between grey-body factors and the amplitudes of gravitational waves from black holes. The correspondence might explain why grey-body factors are more stable, i.e. less sensitive, than higher overtones to small deformation of the effective potential.","external_url":"https://arxiv.org/abs/2406.11694","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-10T14:47:14.038083+00:00","pith_arxiv_id":"2406.11694","created_at":"2026-05-10T00:54:49.177548+00:00","updated_at":"2026-07-10T14:47:14.038083+00:00","title_quality_ok":true,"display_title":"Correspondence between grey-body factors and quasinormal modes","render_title":"Correspondence between grey-body factors and quasinormal modes"},"hub":{"state":{"work_id":"376b6bd4-d850-4ee3-befc-02b1b700019e","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":29,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2024-12-06T14:31:19+00:00","last_pith_cited_at":"2026-07-08T22:22:08+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":"2026-08-22T02:09:33.556326+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":9},{"context_role":"method","n":3}],"polarity_counts":[{"context_polarity":"background","n":7},{"context_polarity":"use_method","n":3},{"context_polarity":"support","n":1},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
