Galaxy kinematics from counter-dispersed imaging.

DOUGLAS N.G. and TAYLOR K.

Abstract (from CDS):

Determining the internal kinematics of a galaxy from planetary nebulae (PN) is usually a two-step process in which the candidate PN are first identified in a target galaxy and then, in a follow-up run, spectra are obtained. We have implemented a new technique in which two dispersed images at the wavelength of the [Oiii] emission line at 5007A{ring} are combined to yield positions, magnitudes and velocities of the PN population in a single step. A reduction in observing time of about a factor of 2 is attainable. We present here the proof-of-principle results.
