CRISTAL is an ALMA Cycle 8 Large Program targeting the [CII] 158 μm line and dust continuum in 19 main-sequence, star-forming galaxies at z~4−5. With the combination of ALMA, HST, and JWST, CRISTAL will produce a systematic census of the gas, dust, and stars on kiloparsec scales when the Universe was only ∼1 billion years old.

This will allow us to connect the properties of the interstellar medium (ISM), circumgalactic medium, star formation, and feedback in the form of outflows. The CRISTAL program will be led from Chile by R. Herrera-Camus (PI, UdeC), M. Aravena (co-PI, UDP), J. González-López (co-PI, Las Campanas Observatory; UDP), together with a team of ~40 scientists from around the world, including co-PIs N. Forster-Schreiber (MPE, Germany), I. De Looze (Ghent U., Belgium), J. Spilker (U. Texas A&M, USA), and K. Tadaki (SOKENDAI, Japan).
