NED Abstract

Copyright by Royal Astronomical Society. 2004MNRAS.352..721E The SAURON project - III. Integral-field absorption-line kinematics of 48 elliptical and lenticular galaxies Emsellem, Eric; Cappellari, Michele; Peletier, Reynier F.; McDermid, Richard M.; Bacon, R.; Bureau, M.; Copin, Y.; Davies, Roger L.; Krajnovic, Davor; Kuntschner, Harald; Miller, Bryan W.; Tim de Zeeuw, P. Abstract. We present the stellar kinematics of 48 representative elliptical and lenticular galaxies obtained with our custom-built integral-field spectrograph SAURON operating on the William Herschel Telescope. The data were homogeneously processed through a dedicated reduction and analysis pipeline. All resulting SAURON data cubes were spatially binned to a constant minimum signal-to-noise ratio. We have measured the stellar kinematics with an optimized (penalized pixel-fitting) routine which fits the spectra in pixel space, via the use of optimal templates, and prevents the presence of emission lines to affect the measurements. We have thus generated maps of the mean stellar velocity V, the velocity dispersion {sigma}, and the Gauss-Hermite moments h_3_ and h_4_ of the line-of-sight velocity distributions. The maps extend to approximately one effective radius. Many objects display kinematic twists, kinematically decoupled components, central stellar discs, and other peculiarities, the nature of which will be discussed in future papers of this series.
