Supersonic relative velocities between baryons and dark matter in the nascent Universe affect the formation and growth of the first galaxies, by impeding the accretion of gas into the potential wells of the dark matter haloes. In turn, this can delay the onset of the formation of the first stars and as such is an important effect to consider in the context of the first galaxies. I will talk about our work self-consistently sampling the relative velocity in a cosmological zoom simulation and discuss some future avenues of exploration.
