The ALMA-CRISTAL Survey: Spatial extent of [CII] line emission in star-forming galaxies at z=4-6

We investigate the spatial extent of the [CII] line emission in a sample of 34 galaxies at z=4-6 from the ALMA-CRISTAL Survey. By modeling the [CII] line emission in the visibility data directly, we derive the effective radius of [CII] line emission assuming exponential distribution. These measurements comprise not only...
