We investigate the birth and formation of primordial structures at early times via 3D numerical N-body, hydro, chemistry simulations including gas cooling, star formation, feedback effects and stellar evolution for stars with different masses and according to corresponding metal yields and lifetimes. This allows us to address physical and luminous properties of primordial stars and galaxies; the interplay between matter and radiation on cosmological scales; and the back-reaction of primordial stellar populations on the surrounding medium. Comparisons with current data of primordial cosmic observables, like gamma-ray-burst hosts, Lyman-alpha emitters and damped Lyman-alpha systems are finally proposed.
