An analysis of two post-starburst galaxies at high redshift indicates the presence of ongoing feedback between the stellar material and the supermassive black hole.

Spatially resolved JWST spectroscopy of a massive, quiescent galaxy at a redshift of ~4 reveals that it formed its stars and quenched rapidly, despite being surrounded by an abundant gas reservoir and gravitationally bound to a star-bursting companion.

A massive galaxy hosting an accreting supermassive black hole two billion years after the Big Bang shows fast neutral-gas outflows that are capable of stopping star formation by removing its fuel while the stars keep rotating in a disk.

A dormant supermassive black hole at high redshift that is substantially overmassive relative to its host galaxy has been detected, indicating a much larger population of dormant black holes around the epoch of reionization.

The authors report the photometric detection of the distant spectroscopically confirmed galaxy JADES-GS-z14-0 at z > 14 with JWST/MIRI. The inferred properties suggest rapid mass assembly and metal enrichment during the earliest phases of galaxy formation.

Spectroscopy from the JWST Advanced Deep Extragalactic Survey of a galaxy at redshift 13 shows a singular, bright emission line identified as Lyman-α, suggesting the onset of reionization only 330 Myr after the Big Bang.

Over the last ten billion years, star formation in the Universe has been on the decline. Astronomers met at the University of Cambridge to discuss causes and themes of galaxy quenching.

Evidence is found for a distant galaxy growing inside-out within the first 700 million years of the Universe. The galaxy has a dense central core comparable in mass density to local massive ellipticals, and an extended star-forming disc.

Analysis of the JWST/NIRSpec spectrum of the recently observed Lyman-break galaxy JADES-GS+53.15508-27.80178 revealed a redshift of z = 7.3, a Balmer break and a complete absence of nebular emission lines, indicating that quenching occurred only 700 million years after the Big Bang.

JWST–NIRSpec spectroscopic confirmation of two luminous galaxies is presented, proving that luminous galaxies were already in place 300 million years after the Big Bang and are more common than what was expected before JWST.

As part of the JWST Advanced Deep Extragalactic Survey (JADES), NIRSpec has spectroscopically confirmed four young and metal-poor galaxies at redshift 10.3–13.2, from an early epoch of galaxy formation.

An extensive analysis of the JWST-NIRSpec spectrum of GN-z11 shows a supermassive black hole of a few million solar masses in a galaxy 440 million years after the Big Bang.

An (ultraviolet) dust attenuation feature at 2,175 Å, attributed to carbonaceous dust grains in the Milky Way and nearby galaxies, also exists in galaxies up to a redshift of 7.

Α combined study of spatially resolved stellar kinematics and global stellar populations with the SAMI Galaxy Survey finds a strong correlation between the characteristic stellar population age of a galaxy and its intrinsic ellipticity.
