The Fundamental Properties of Early-type Galaxies in the Coma Cluster
Stephen A. W. Moore, J. R. Lucey, H. Kuntschner +2
We report the results of a high quality spectral study of early-type galaxies within the Coma Cluster core. Stellar population analysis using Lick/IDS indices to break the age/meta…
Distinguishing Local and Global Influences on Galaxy Morphology: An HST Comparison of High and Low X-ray Luminosity Clusters
Michael Balogh, Ian Smail, R. Bower +6
(Abridged) We present a morphological analysis of 17 X-ray selected clusters at z~0.25, imaged uniformly with HST WFPC2. Eight of these clusters have low X-ray luminosities (<10^{4…
SAURON: An Innovative Look at Early-Type Galaxies
M. Bureau, R. Bacon, M. Cappellari +9
A summary of the SAURON project and its current status is presented. SAURON is a panoramic integral-field spectrograph designed to study the stellar kinematics, gaseous kinematics,…
Ionized Gas in Spheroids: The SAURON Survey
D. Krajnovic, R. Bacon, M. Bureau +11
Early results are reported from the SAURON survey of the kinematics and stellar populations of nearby cluster and field E, S0, and Sa galaxies. We present maps of the Hbeta and [OI…
On the Origin of the Colour-Magnitude Relation in the Virgo Cluster
Alexandre Vazdekis, Harald Kuntschner, Roger L. Davies +3
We explore the origin of the colour-magnitude relation (CMR) of early type galaxies in the Virgo cluster using spectra of very high S/N ratio for six elliptical galaxies selected a…
The SAURON project. I. The panoramic integral-field spectrograph
R. Bacon, Y. Copin, G. Monnet +10
A new integral-field spectrograph, SAURON, is described. It is based on the Tiger principle, and uses a lenslet array. SAURON has a large field of view and high throughput, and all…
Line-of-sight velocity distributions of low-luminosity elliptical galaxies
C. Halliday, Roger L. Davies, Harald Kuntschner +4
The shape of the line-of-sight velocity distribution (LOSVD) is measured for a sample of 14 elliptical galaxies, predominantly low-luminosity ellipticals. The sample is dominated b…
