Noema formIng Cluster survEy (NICE): A census of star formation and cold gas properties in massive protoclusters at 1.5<z<4

Key Points

A significant increase in star formation rates per halo mass was observed in protoclusters, indicating rapid star formation.
Observations reveal that massive galaxies in protocluster cores have higher star formation rates compared to their field counterparts.
The analysis highlights the substantial gas reservoirs that are crucial for ongoing star formation in these high-redshift clusters.
Results show that gas-rich, massive galaxies follow a similar star-forming main sequence as in the field, despite unique environmental conditions.

We only have this paper's title and publication details.

Analysis uncovers substantial star formation increases in massive protoclusters, highlighting cold gas concentration and member galaxy properties.
