COSMOS2020: Discovery of a Protocluster of Massive Quiescent Galaxies at z = 2.77

COSMOS2020: Discovery of a Protocluster of Massive Quiescent Galaxies at z = 2.77

Protoclusters of galaxies have been found in the last quarter-century. However, most of them have been found through the overdensity of star-forming galaxies, and there have been no known structures identified by more than two spectroscopically confirmed quiescent galaxies at z > 2.5. In this let...
