Abstract: The fundamental nature of dark matter so far eludes direct detection experiments, but it has left its imprint in the cosmic large-scale structure. Extracting this information requires accurate modelling of structure formation for different dark matter
theories, careful handling of astrophysical uncertainties and consistent observations in independent cosmological probes. I will review a multi-scale, multi-epoch test of the nature of dark matter combining observations of the cosmic microwave background,
galaxy clustering (redshift z < 2), the Lyman-alpha forest (2 < z < 5) and the high-redshift (z > 5) galaxy UV luminosity function from the Hubble and Webb Space Telescopes. I will show that both the S_8 cosmological parameter discrepancy and a new five-sigma
tension in inference of the small-scale matter power spectrum can be resolved by a contribution of ultra-light axion dark matter with particle masses ~ 10^-25 eV. I will discuss prospects for adjudicating the viability of dark matter solutions in observations
of the galaxy and Milky Way sub-structure distributions in the transformative Vera Rubin Observatory.</div>
