The ALPINE-ALMA [CII] survey - Small Lyα-[CII] velocity offsets in main-sequence galaxies at 4.4 < z < 6

Context. The Lyman-α line in the ultraviolet (UV) and the [CII] line in the far-infrared (FIR) are widely used tools to identify galaxies in the early Universe and to obtain insights into interstellar medium (ISM) properties in high-redshift galaxies. By combining data obtained with ALMA in band 7 at ∼320 …
