Originating Calendar: Astronomy Colloquium Speaker Calendar; Though it might seem simple or amateurish, one can often learn a lot about galaxies just by looking at them. Telescopes like Hubble and Webb have allowed us to image the starlight of galaxies in detail even out to high redshifts, but due to the daunting technical requirements, we have much less detailed information about the distribution of cold gas and dust within early-universe galaxies. I will present an overview and some early results from the CRISTAL survey, a large ALMA program designed to map the gas and dust in ~40 typical 4 < z < 6 galaxies at kiloparsec physical resolution. The survey reveals diverse morphologies and kinematics, including rotating disk galaxies, merging systems, gas-rich tidal tails, and clumpy star formation. The resulting dataset provides a detailed view of gas, dust, and stellar structures on kiloparsec scales at the end of the era of reionization, enabling a wide range of spatially-resolved multiwavelength studies of high-redshift galaxies.
