With ten times the sensitivity of Advanced LIGO, Cosmic Explorer will push gravitational-wave astronomy towards the edge of the observable universe ($z \\sim 100$). The goals of this Horizon Study are to describe and evaluate design concepts for Cosmic Explorer; to plan for the United States' leadership in gravitational-wave astronomy; and to envisage the role of Cosmic Explorer in the international effort to build a \"Third-Generation\" (3G) observatory network that will make discoveries transformative across astronomy, physics, and cosmology.","external_url":"https://arxiv.org/abs/2109.09882","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T08:05:30.842224+00:00","pith_arxiv_id":"2109.09882","created_at":"2026-05-09T06:19:14.362369+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":true,"display_title":"A Horizon Study for Cosmic Explorer: Science, Observatories, and Community","render_title":"A Horizon Study for Cosmic Explorer: Science, Observatories, and Community"},"hub":{"state":{"work_id":"66f86576-23ec-4509-96d3-5a47135d55f1","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":68,"external_cited_by_count":null,"distinct_field_count":7,"first_pith_cited_at":"2022-03-11T18:13:52+00:00","last_pith_cited_at":"2026-05-22T12:19:56+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":"2026-06-19T20:17:54.647221+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":22},{"context_role":"method","n":2},{"context_role":"dataset","n":1}],"polarity_counts":[{"context_polarity":"background","n":22},{"context_polarity":"use_method","n":2},{"context_polarity":"use_dataset","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
