The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

Over the past decades, rest-frame ultraviolet (UV) observations have provided large
samples of UV luminous galaxies at redshift (z) greater than 6 (refs.,–), during the so-called …

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 …

Context. Molecular gas is a necessary fuel for star formation. The CO (1− 0) transition is
often used to deduce the total molecular hydrogen but is challenging to detect in low …

Recent observations with the JWST are yielding tantalizing hints of an early population of
massive, bright galaxies at z> 10, with Atacama Large Millimeter/submillimeter Array (ALMA) …

We explore the kinematics of 27 z≳ 6 quasar host galaxies observed in [C ii] 158 μm ([C ii])
emission with the Atacama Large Millimeter/submillimeter Array at a resolution of≈ 025. We …

The [C II] 158 μm line is one of the strongest IR emission lines, which has been shown to
trace the star formation rate (SFR) of galaxies in the nearby Universe, and up to z∼ 2 …

We present a joint analysis of the galaxy S04590 at z= 8.496 based on NIRSpec, NIRCam,
and NIRISS observations obtained as part of the Early Release Observations program of the …

We investigate the fine-structure [C ii] line at 158 μm as a molecular gas tracer by analyzing
the relationship between molecular gas mass (M mol) and [C ii] line luminosity (L [C II]) in …

At redshift z> 5, the far-infrared (FIR) continuum spectra of main-sequence galaxies are
sparsely sampled, often with a single data point. The dust temperature T d, SED, thus has to …
