| Abstract: In the standard cosmological model, the main non-baryonic component is defined by its acronym: Cold Dark Matter (CDM). In this talk I will show how measurements of the clustering of galaxies on scales larger than roughly 10 Mpc can place leading constraints on the physical properties behind each one of the acronym's letters, provided non-linearities in the matter distribution due to new physics are properly modeled via effective theories. Worked out examples will include ultra-light axions, strong kinetic coupling at late times, and tests of the equivalence principle in the dark sector. |
