Spitzer Planck Herschel Infrared Cluster (SPHerIC) survey: Candidate galaxy clusters at 1.3 < z < 3 selected by high star-formation rate

C. Martinache, A. Rettura, H. Dole +17

There is a lack of large samples of spectroscopically confirmed clusters and protoclusters at high redshifts, 1.5. Discovering and characterizing distant (proto-)clusters is im…
