New constraints on primordial features from the galaxy two-point correlation function

Features in the primordial power spectrum represent imprinted signal density perturbations of physics and evolution early Universe. A measurement such signals will represents need to go beyond minimal assumption made for initial conditions cosmological perturbations. For first time, we study different templates with undamped oscillations or a bump from two-point correlation function measured BOSS DR12 galaxies constraining amplitude features be at most few percent. Constraints are competitive ones obtained {\em Planck} DR3.
