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…
Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model
Lucie Scharré, Michaela Hirschmann, Adèle Plat +10
Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extrem…
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…
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…
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\…
The Pandora project. II: how non-thermal physics drives bursty star formation and temperate mass-loaded outflows in dwarf galaxies
Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt +11
Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation his…
