Description
From cosmological observations we know that DM must display clustering properties similar to CDM, at least on the largest scales. The linear LSS observations, and CMB observations can be used to place very stringent constraints although at smaller scales the situation remains unclear. This points to a need to study plausible dark matter models that allow for significant deviation from ΛCDM models at small scales. I will discuss two class of such models (non-trivial axion and neutrino physics) and will discuss how high-redshift universe can give smoking gun signature of these models.
