The combination of JWST and ALMA data here unravel the history of the gas content of a quiescent galaxy, which became quenched through an act of self-sabotage. Black-hole accretion feedback heated the galaxy’s surrounding material, preventing its accretion.

A combination of JWST/NIRCam observations and magnetohydrodynamic simulations indicates that frequent mergers with close companions give rise to bursty star formation and hence the unexpectedly high Lyman-α emission detected from early galaxies.

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.

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.

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.

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.

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.

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.

Lyman-alpha emission is one of the observational probes for the high-redshift universe. Here, the authors show several Lyman-alpha emitting companion galaxies around the hot dust-obscured galaxy W0410-091 suggesting that the galaxy evolves in a very dense environment.

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.

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.

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.

The JWST Advanced Deep Extragalactic Survey using NIRCam to find the earliest galaxies reveals the size and star formation rates of four extreme redshift (z > 10) galaxies of the distant Universe.

Observation of the emission line of doubly ionized oxygen at a redshift of 9.1096 reveals that star formation began at a redshift of about 15, around 250 million years after the Big Bang.

A study reporting optical and near-infrared observations of quasars at redshifts 5.8–6.6 shows that about half have strong winds, up to 17% the speed of light, suppressing black-hole growth.

Star formation at a rate of more than 15 solar masses a year has been observed inside a massive outflow of gas from a nearby galaxy; this could also be happening inside other galactic outflows.
