Extended enriched gas in a multi-galaxy merger at redshift 6.7

JWST data reveal a multi-galaxy merger 800 Myr after the Big Bang, likely a progenitor of massive quiescent galaxies seen at later times. Its extended [O iii] halo offers direct evidence of early metal enrichment via tidal stripping.

Spatial variations in aromatic hydrocarbon emission in a dust-rich galaxy

We present James Webb Space Telescope observations that detect the 3.3 μm polycyclic aromatic hydrocarbon feature in a galaxy observed less than 1.5 billion years after the Big Bang.

Accurate oxygen abundance of interstellar gas in Mrk 71 from optical and infrared spectra

A method for measuring oxygen abundances using optical and far-infrared emission lines provides absolute metallicities of the interstellar gas in Markarian 71 and could be applied across cosmic history.

Quenching of star formation from a lack of inflowing gas to galaxies

The authors report 1.3 mm observations of dust emission from strongly lensed galaxies where star formation is quenched, demonstrating that gas depletion is responsible for the cessation of star formation in some high-redshift galaxies.

A dusty star-forming galaxy at z = 6 revealed by strong gravitational lensing

This paper reports the detection of a high-redshift galaxy that may be more representative of ‘normal’ star-forming galaxies formed in the first billion years of the Universe than the extreme starbursts discovered to date.
