Small-scale dark matter structures provide an important window into primordial density fluctuations and the microphysical properties of dark matter. Deviations from the standard LCDM model can significantly alter the formation and evolution of dark matter structures, leading to observational differences in galaxy properties.

In this talk, I will explore how deviations from LCDM impact observations of Milky Way satellite galaxies, such as their central densities and abundance. By modelling dark matter subhalos and their galaxies using a combination of numerical and analytical techniques, I will discuss how these properties constrain the primordial fluctuations and offer insights into specific dark matter models.
