The first observations of the James Webb Space Telescope (JWST) have revolutionized our
understanding of the Universe by identifying galaxies at redshift z≈ 13 (refs.,–). In addition …

Spectroscopy with the James Webb Space Telescope has opened the possibility of
identifying moderate-luminosity active galactic nuclei (AGNs) in the early Universe, at and …

Finding the emergence of the first metals in the early Universe and identifying their origin are
some of the most important goals of modern astrophysics. We present deep JWST/NIRSpec …

We present a study of the environments of 17 Lyman-α emitting galaxies (LAEs) in the
reionisation-era (5.8< z< 8) identified by JWST/NIRSpec as part of the JWST Advanced …

We describe the NIRSpec component of the JWST Deep Extragalactic Survey (JADES), and
provide deep spectroscopy of 253 sources targeted with the NIRSpec micro-shutter …

Dust in galaxies is an important tracer of galaxy properties and their evolution over time. The
physical origin of the grain size distribution, the dust chemical composition, and, hence, the …

We present new multifrequency Atacama Large Millimeter/submillimeter Array (ALMA)
continuum observations of the massive [], UV-luminous [] galaxy REBELS-25 in Bands 3, 4 …

JWST's recent discovery of well-formed galaxies and supermassive black holes only a few
hundred Myr after the big bang seriously challenges the timeline predicted by Λ CDM. Now …

ABSTRACT We present Atacama Large Millimetre/submillimetre Array (ALMA) observations
of the [O iii] 88 emission of a sample of thirteen galaxies at to 7.6 selected as [C ii]-emitting …

We interpret the peculiar supersolar nitrogen abundance recently reported by the James
Webb Space Telescope observations for GN-z11 (z= 10.6) using our state-of-the-art …
