CRISTAL is an ALMA Cycle 8 Large Program that observed in the [CII] 158 μm line and dust continuum 19 main-sequence, star-forming galaxies at z~4−5. With the combination of ALMA, HST, and JWST, CRISTAL produced a systematic census of the gas, dust, and stars on kiloparsec scales when the Universe was only ∼1 billion years old.
We constrained the nature of the galaxies (disk vs. merger), quantified the amount of rotation vs. random motions, and measured the rotation curves and velocity dispersion profiles.

We searched for cold gas outflows on individual galaxies, constraining their occurrence and main properties such as mass and mass loss rates.

We characterized the distribution of the gas, dust and stars on kiloparsec scales. We studied the extended or "halo" emission, exploring its origin and powering mechanism.

We constrained the ISM properties by combining [C II] and dust continuum emission with stellar and UV light measurements from HST and JWST observations.
