Interplay of Compaction, Quenching, and Black Hole Growth in the Most Massive Galaxies since : Insights from JWST and Chandra Data
Novan Saputra Haryana, Masayuki Akiyama, Abdurro'uf +16
The buildup of dense stellar cores is expected to mark an important transition in the star-formation and black-hole growth of massive galaxies. Using spatially resolved spectral en…
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…
The role of small-scale environments in the quenching of massive galaxies at
Takumi Kakimoto, Masayuki Tanaka, Makoto Ando +10
Massive quiescent galaxies (QGs) at high redshifts are likely progenitors of massive elliptical galaxies in the local Universe. Recent discoveries of high-redshift QGs in overdensi…
The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities
Steven Gillman, Kei Ito, Francesco Valentino +25
We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-wa…
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…
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,…
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…
