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…
Dynamical properties and star formation history of a low-mass quenched galaxy at Cosmic Noon
K. Ito, F. Valentino, W. M. Baker +12
We present the spectroscopic confirmation and in-depth analysis of AURORA-LQG1, a low-mass quiescent galaxy at with observed with…
An Ancient Descendant of the First Galaxies
Jacqueline Antwi-Danso, Adam Muzzin, Luke Robbins +18
JWST has revealed unexpectedly bright galaxies in the first 500 Myr after the Big Bang. Their overabundance suggests that they are preferentially observed during burst phases, wher…
Even redder than we knew: color and evolution up to from JWST/NIRCam photometry
A. van der Wel, M. Martorano, D. Marchesini +14
JWST/NIRCam provides rest-frame near-IR photometry of galaxies up to with exquisite depth and accuracy. This affords an unprecedented view of the evolution of the UV-optica…
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\…
