题目：A Massive Protocluster Anchored by a Luminous Quasar at z=6.63

摘要：Protoclusters, the progenitors of galaxy clusters, trace large scale structures in the early Universe and are important to our understanding of structure formation and galaxy evolution. Only a handful of protoclusters have been identified in the Epoch of Reionization,and distant quasars that host active supermassive black holes are thought to reside in the most massive dark matter halos at that cosmic epoch and could thus potentially pinpoint some of the earliest protoclusters. In the Letter, authors report the discovery of a massive protocluster around a luminous quasar at z = 6.63. This protocluster is anchored by the quasar and includes three [C II] emitters at z ～ 6.63, 12 spectroscopically confirmed Lyα emitters (LAEs) at 6.54 < z =< 6.64, and a large number of narrow-band-imaging selected LAE candidates at the same redshift. This structure has an overall overdensity of about 3.3 within ～35 × 74 cMpc2. They estimate that this protocluster will collapse into a galaxy cluster with a mass of about 6.9×10^15 M⊙ at the current epoch, more massive than the most massive clusters known in the local Universe.
