NEFERTITI-ERC

The goal of NEFERTITI (NEar-FiEld cosmology Re-Tracing Invisible TImes) is to make a major step forward in our understanding of the first stars and galaxies by catching the stellar fossils from the early Universe in our Galactic neighborhood. To this end we are exploiting a novel approach which integrates theory and observations in a unique way.
