Description
UV luminosity functions (LF), measured with the Hubble Space Telescope, provide a wealth of information on the state of the early Universe. This probe tracks the evolution of the mass function of dark-matter halos at earlier times (z=4-10) and lower masses than the local Universe, an interesting regime to constrain the nature of dark matter and primordial fluctuations at small scales. In this talk I will show how to use UVLF data to learn about cosmology, focusing on primordial non-Gaussianity and set constraints on the non-Gaussianity amplitude fNL at small scales, beyond the reach of the CMB.
