NOEMA formIng Cluster survEy (NICE): Characterizing eight massive galaxy groups at 1.5 < z < 4 in the COSMOS field

The NOEMA formIng Cluster survEy (NICE) is a large program targeting 69 massive galaxy group candidates at z>2 in six deep fields. We report spectroscopic confirmation of eight groups at 1.65\leq z\leq3.61 in COSMOS. Homogeneously selected as significant overdensities of red IRAC sources with red Herschel colors, four groups are... Show more
