JADES: the mass-metallicity relation at . New calibrations, extremely metal-poor galaxies, and chemical diversity

Yuki Isobe, Mirko Curti, Roberto Maiolino +28

We present gas-phase metallicities of star-forming galaxies at -10 with deep JWST/NIRSpec spectra from the JADES full data release, Dark Horse, and OASIS programmes. We stack…

A Steep-Extinction QSO at z=4.6: JWST Evidence for Abundant Small Dust Grains

Mingyu Li, Zheng Cai, Roberto Maiolino +9

The rapid accumulation of massive dust reservoirs in the early Universe remains a major challenge in astrophysics. While core-collapse supernovae can inject large dust grains ($a \…

JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: stellar population catalogue for galaxies in GOODS-N and GOODS-S

Qiao Duan, Sandro Tacchella, Benjamin D. Johnson +37

We present the galaxy stellar population catalogue from the JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5 (DR5), providing homogeneous Bayesian inference of physic…

Metal Mayhem at : Diversity and Evolution of Gas-Phase Metallicity Gradients

Maria Koller, Roberto Maiolino, Hannah Übler +16

We present a JWST/NIRSpec-IFU study of metallicity gradients in seven low-metallicity systems at . The main sample spans stellar masses of $\rm \log(M_*/M_{\odot}) \sim…

GA-NIFS: Dissecting The Alchemised: JWST reveals turbulent metal-poor gas fuelling a co-spatial starburst in a complex system at

Robert G. Pascalau, Francesco D'Eugenio, Roberto Maiolino +26

Recent observations revealed that distant galaxies have bursty star formation histories, regulated by stellar or active galactic nuclei (AGN) feedback and gas inflows. According to…

When relics were made: vigorous stellar rotation and low dark matter content in the massive ultra-compact galaxy GS-9209 at z=4.66

Robert G. Pascalau, Francesco D'Eugenio, Sandro Tacchella +24

JWST uncovered a large number of massive quiescent galaxies (MQGs) at , which theoretical models struggle to reproduce. Explaining the number density of such objects requires…
