Lambda Cold Dark Matter (LCDM) is the most successful theory for the formation of structure in the Universe. Although its predictions have been verified on large scales, they are still contested on the scale of dwarf galaxies, whose dynamical properties are often cited as evidence for the need to revise some of LCDM’s basic tenets. In this context, I will discuss the recent discovery of the faintest galaxies known to date, and how their properties may be used to place constraints on the clustering of dark matter on the smallest galactic and sub-galactic scales, as well as on the viability of some of the proposed alternatives to LCDM.

About the speaker: Julio Navarro is a Landsdowne science professor of Astrophysics at the University of Victoria, Canada. He is an internationally recognized name in the fields of theoretical galaxy formation, dark matter and cosmology. More specifically, he has a number of pioneering works in the studying the structure of cold dark matter halos (Navarro-Frenk-White halo profile) and their substructures.
