Unveiling the population of massive quenched galaxies at in the COLIBRE simulations -- II. The role of AGN feedback and environment on their emergence
Ãngel Chandro-Gómez, Claudia del P. Lagos, Chris Power +16
Early () Massive (), Quenched Galaxies (MQGs) challenge current galaxy formation models. In this series, we study these…

High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift
F. Valentino, K. Ito, M. Farcy +31
We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent…

DeepDive: A deep dive into the physics of the first massive quiescent galaxies in the Universe
K. Ito, F. Valentino, G. Brammer +26
We present the DeepDive program, in which we obtained deep JWST/NIRSpec G235M/F170LP spectra for ten primary massive () quiescent galaxies at $z\…
