Morphology, sizes, and scatter in a large sample of distant quiescent galaxies
G. Scarpe, F. Valentino, K. Ito +3
After quenching galaxies keep growing in size across time, as established in the literature up to cosmic noon. In this work, we assemble one of the largest and most comprehensive m…

DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Proto-clusters
Takumi Kakimoto, Masayuki Tanaka, Kei Ito +19
We report on the spectroscopic confirmation of overdense regions of massive quiescent galaxies (QGs) in the early Universe with JWST/NIRSpec. Based on data from the DeepDive NIRSpe…
