The Planetary Nebula Spectrograph elliptical galaxy survey: the dark matter in NGC 4494
Merrifield is the UK leader of the international (UK/Netherlands/Australia/Italy/US/Germany) PN.S project, having been involved since its inception, and was principal investigator of the UK’s contribution to building the custom-designed novel spectrograph, funded by the Royal Society. Merrifield was the principal author of the proposal seeking the PNe data set for NGC 4494 published here, and was PI for more than half of the observing time that resulted in these data. He contributed extensively to the Jeans modelling presented; in particular, the analysis of higher order moments used to lift the anisotropy degeneracy followed directly from his previous work.
