The Lambda Cold Dark Matter theory has condensed as the central paradigm of cosmology, providing an evolutionary description that is tractable to numerical simulation. The self-similarity of the dark matter halos that emerge from this - in terms of their (i) mass function, (ii) satellite mass function and (iii) inner density slopes - appear difficult to simultaneously reconcile with low mass galaxies, even with the invocation of baryonic effects. One mechanism that can alleviate the tension between these and observed dwarfs is the inclusion of self-interaction channels for cold dark matter.
