Wide-Field Multi-Object Spectrograph

(proposed instrument to detect baryon acoustic oscillations)

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

The WFMOS was intended for one of the Gemini Observatory telescopes and later the Subaru Telescope and a new plan (the Subaru PFS Spectrograph) is aimed at its niche.
