An extended [C II] halo around a massive star-forming galaxy at z = 5.3

High-redshift observations are often biased towards massive and bright galaxies that do not necessarily represent the full population. In order to accurately study galaxy evolution and mass assembly at these redshifts, observations of ‘normal’ main sequence galaxies are required. Here we present Atacama Large Millimeter/Submillimeter Array (ALMA) 0.3 arcsec resolution observations of the [C II] […]

Structure and kinematics of a massive galaxy at z ∼ 7

Observations of the rest-frame UV emission of high-redshift galaxies suggest that the early stages of galaxy formation involve disturbed structures. Imaging the cold interstellar medium (ISM) can provide a unique view of the kinematics associated with the assembly of galaxies. In this paper, we analyze the spatial distribution and kinematics of the cold ionized gas

Revealing the Nature of a Lyα Halo in a Strongly Lensed Interacting System at z = 2.92

Spatially extended halos of H I Lyα emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of these halos is still hampered by the complex radiative transfer effects of the Lyα line and limited angular resolution. In this paper, we present resolved Multi Unit Spectroscopic Explorer
