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…
MAGAZ3NE: Spatially Resolved Ages and Chemical Abundances of Ultra-Massive Quiescent Galaxies at z 3.5 using JWST/NIRSpec IFU
Adit H. Edward, Jacqueline Antwi-Danso, Adam Muzzin +14
We present spatially-resolved measurements of stellar age, [Fe/H], and [/Fe] in three ultra-massive (), compact ( kpc) qui…
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…
A Spectral Atlas for Quiescent Galaxies
Massissilia L. Hamadouche, Jacqueline Antwi-Danso, Aliza Beverage +1
Key absorption features in the spectra of massive quiescent galaxies reveal a wealth of information about their stellar populations and, in some cases, the properties of gas within…
The JWST EXCELS Survey: gas-phase metallicity evolution at 2 < z < 8
T. M. Stanton, F. Cullen, A. C. Carnall +15
We present an analysis of the gas-phase mass-metallicity relationship (MZR) and fundamental metallicity relationship (FMR) for star-forming galaxies at from the JW…
DeepDive: Tracing the early quenching pathways of massive quiescent galaxies at from their star-formation histories and chemical abundances
Massissilia L. Hamadouche, Katherine E. Whitaker, Francesco Valentino +21
We investigate the chemical abundances and star-formation histories (SFH) of ten massive () quiescent galaxies at usi…
