One cloud is not enough: Extreme conditions biasing chemical abundances in high-redshift galaxies

Since its launch, JWST has enabled the characterisation of the ionised interstellar medium (ISM) of high-redshift galaxies using a range of rest-frame ultraviolet (UV) and optical diagnostics originally developed in the Local Universe. These observations challenge the validity of such classical methods in extreme high-...

JADES: The Star Formation and Dust Reddening Properties of Galaxies at 3 < z < 7

We present the star formation and dust content properties for a sample of 646 galaxies at redshifts 3 < z < 7 as part of the JADES survey. Our analysis is based on measurements of the Hα/Hβ Balmer decrement using medium resolution (R ∼ 1000) spectroscopic observations with the JWST/NIRSpec microshutter assembly. Stella...
