Wide-Field Multi-Object Spectrograph

(proposed instrument to detect baryon acoustic oscillations)

The Wide-Field Multi-Object Spectrograph (WFMOS) is a proposed instrument for research in Cosmology. It aims to identify many distant galaxies with information about their positions, under the assumption that this will show a tendency for galaxies to be found 150 Parsecs (pc) distant from each other, a signature of Baryon Acoustic Oscillations (BAO).

The WFMOS was intended for one of the Gemini Observatory telescopes but now the Subaru Telescope is its intended host.
