Quiescent fractions in high-redshift galaxy groups reflect their hot-or-cold state of gas accretion
Guillaume Elias, Emanuele Daddi, Chiara D'Eugenio +15
Cold accretion and quenching are closely related aspects of galaxy evolution, as sustained gas supply is required to maintain star formation. High-redshift galaxy groups therefore…

Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are…

Noema formIng Cluster survEy (NICE): A Census of Star Formation and Cold Gas Properties in Massive protoclusters at 1.5<z<4
Luwenjia Zhou, Tao Wang, Emanuele Daddi +36
Massive protoclusters at z~1.5-4, the peak of the cosmic star formation history, are key to understanding the formation mechanisms of massive galaxies in today's clusters. However,…
