Scientific paper

Galactic distance indicators, particularly the Fundamental Plane and the Tully-Fisher relations are discussed. These have both been widely used to measure large-scale motions of galaxies in the local universe and to extract cosmological information. However these indicators can be calibrated using nearby galaxies such as those in the local group and modelled using detailed N-body simulations and observations of stellar populations. These considerations provide a bridge between distant and nearby extragalactic objects and their stars.
