Description

In its most basic form, the highly successful $\Lambda$CDM cosmology can be encapsulated in six parameters. Once these parameters are specified, so too is a wide variety of phenomena, from fluctuations in the microwave background to the growth of structure to the evolution of the expansion rate of the Universe. I will review the predictions related to cosmological structure formation, focusing on areas where potential tensions have emerged: these include nonlinear scales at the earliest times and smallest mass scales and comparisons between measurements early and late in the Universe's history.
