Beyond orientation: Evidence for distinct physical regimes among Little Red Dots and Little Blue Dots
L. Barrufet, J. S. Dunlop, M. L. Hamadouche +6
Little Red Dots (LRDs) and Little Blue Dots (LBDs) may represent the same population of compact active galactic nuclei (AGN) observed along different lines of sight. We test this s…
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 s…
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) quie…
DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Overdensities
Takumi Kakimoto, Masayuki Tanaka, Kei Ito +20
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…
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…
