Taurus – Co-inventor

Taurus is an Imaging Fabry-Perot spectrometer developed by Keith Taylor of the Royal Greenwich Observatory and Paul Atherton from IC Physics. It was used to make Doppler radial velocity field images of emission line gas in galaxies and nebulae to understand their dynamics.

Following the success of this instrument a User Instrument version was developed for the WHT in La Palma and for the AAT in Australia. Tests using the focal reducer in Taurus and a Grism led to the subsequent development of the Low Dispersion Survey Spectrograph (LDSS), using photo etched masks in the focal plane to enable multi object spectroscopy of very faint objects.
