We study ground- and excited-state properties of medium-mass nuclei based on chiral two- and three-nucleon interactions. Our results are based on a many-body perturbation theory approach combined with large-scale diagonalizations. In particular, we will focus on theoretical uncertainty estimates by considering Hamiltonians at different resolution and different sets of low-energy constants.
