Findings

Compilation of current census of extragalactic binaries

Discussion of techniques for detecting eclipsing binaries

Emphasis on binaries as distance indicators and probes of massive stars

Abstract

I present an overview of the techniques used for detecting and following up binaries in nearby galaxies and present the current census of extragalactic binaries, with a focus on eclipsing systems. The motivation for looking in other galaxies is the use of eclipsing binaries as distance indicators and as probes of the most massive stars.
