We used the multi-telescope interferometric combiners MIRC and PIONIER to detect and measure the astrometric positions of the high-contrast companions orbiting 16 bright Galactic Cepheids. We made use of the CANDID algorithm to search for the companions and set detection limits. We also present new high-precision RVs which were used to fit radial pulsation and orbital velocities. We report the detection of the companions orbiting the Cepheids U Aql, BP Cir, and S Mus","authors_text":"A. Gallenne, A. M\\'erand, F. Baron, G. H. Schaefer, G. Pietrzy\\'nski, J. D. Monnier, N. R.
