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…
There and back again? Neutral outflows in z~3.5 quiescent galaxies
Pengpei Zhu, Kei Ito, Francesco Valentino +16
Neutral gas outflows play a crucial role in the baryon cycle of galaxies, their properties provide key insights into the transition from star formation to quiescence. In this work,…
The ALMaQUEST Survey XIII: Understanding radial trends in star formation quenching via the relative roles of gas availability and star formation efficiency
Hsi-An Pan, Lihwai Lin, Sara L. Ellison +7
Star formation quenching is one of the key processes that shape the evolution of galaxies. In this study, we investigate the changes in molecular gas and star formation properties…
The ALMaQUEST Survey XII: Dense Molecular Gas as traced by HCN and HCO in Green Valley Galaxies
Lihwai Lin, Hsi-An Pan, Sara L. Ellison +11
We present ALMA observations of two dense gas tracers, HCN(1-0) and HCO(1-0), for three galaxies in the green valley and two galaxies on the star-forming main sequence with c…
