Spt2349-56: The Most Massive And Active Proto-Cluster Known At Z=4.3

As part of the follow-up of bright 1.4mm sources from the South Pole Telescope 2500 square degree survey, we have identified a unique proto-cluster at z=4.3. Using ALMA CO(4-3) and [CII] spectroscopy, we have spectroscopically confirmed at least 12 members within a radius of 13 arcseconds. These 12...
