Determining Accurate Distances to Nearby Galaxies
Abstract
Description
We have undertaken several projects with the purpose of determining accurate distances to nearby galaxies to calibrate the extragalactic distance scale. Specifically, I describe the DIRECT project which aims to derive the distance to M31 and M33 directly, using detached eclipsing binaries and the Baade-Wesselink method for Cepheids. I also present a ``hybrid'' method of discovering Cepheids with ground-based telescopes using image subtraction and then following them up with the HST to derive Cepheid period-luminosity distances.
