Recovering the intrinsic shape of early-type galaxies
Remco C. E. van den Bosch, Glenn van de Ven
We investigate how well the intrinsic shape of early-type galaxies can be recovered when both photometric and two-dimensional stellar kinematic observations are available. We simul…
The SAURON project - XII. Kinematic substructures in early-type galaxies: evidence for disks in fast rotators
Davor Krajnovic, R. Bacon, Michele Cappellari +10
[Abridged] We analysed two-dimensional maps of 48 early-type galaxies obtained with the SAURON and OASIS integral-field spectrographs using kinemetry, a generalisation of surface p…
Recovery of the internal orbital structure of galaxies
G. van de Ven, P. T. de Zeeuw, R. C. E. van den Bosch
We construct axisymmetric and triaxial galaxy models with a phase-space distribution function that depends on linear combinations of the three exact integrals of motion for a separ…
Triaxial orbit based galaxy models with an application to the (apparent) decoupled core galaxy NGC 4365
R. C. E. van den Bosch, G. van de Ven, E. K. Verolme +2
We present a flexible and efficient method to construct triaxial dynamical models of galaxies with a central black hole, using Schwarzschild's orbital superposition approach. Our m…
The shape of the dark matter halo in the early-type galaxy NGC 2974
Anne-Marie Weijmans, Davor Krajnovic, Glenn van de Ven +3
We present HI observations of the elliptical galaxy NGC 2974, obtained with the Very Large Array. These observations reveal that the previously detected HI disc in this galaxy (Kim…
Fast and Slow Rotators: The build-up of the Red Sequence
Eric Emsellem, Michele Cappellari, Davor Krajnovic +11
Using the unique dataset obtained within the course of the SAURON project, a radically new view of the structure, dynamics and stellar populations of early-type galaxies has emerge…
Recent Star Formation in Nearby Early-type Galaxies
M. Sarzi, R. Bacon, M. Cappellari +9
Motivated by recent progress in the study of early-type galaxies owing to technological advances, the launch of new space telescopes and large ground-based surveys, we attempt a sh…
Towards a new classification of early-type galaxies: an integral-field view
J. Falcón-Barroso, R. Bacon, M. Cappellari +9
In this proceeding we make use of the two-dimensional stellar kinematics of a representative sample of E and S0 galaxies obtained with the SAURON integral-field spectrograph to rev…
Absorption line-strengths of 18 late-type spiral galaxies observed with SAURON
Katia Ganda, Reynier F. Peletier, Richard M. McDermid +10
We present absorption line-strength maps for a sample of 18 Sb-Sd galaxies observed using the integral-field spectrograph SAURON. The SAURON spectral range allows the measurement o…
The SAURON project -- IX. A kinematic classification for early-type galaxies
Eric Emsellem, Michele Cappellari, Davor Krajnovic +10
2D stellar kinematics of 48 representative E and S0 galaxies obtained with the SAURON IFS reveal that early-type galaxies appear in two broad flavours, depending on whether they ex…
The Nature of Galactic Bulges from SAURON Absorption Line Strength Maps
Reynier F. Peletier, Jesus Falcon-Barroso, Katia Ganda +10
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H, Mg b and Fe 5015 we derive SSP-ages and metallicities.…
Stars and Gas in the Inner Parts of Galaxies seen in SAURON Integral Field Observations
R. F. Peletier, K. Fathi, E. L. Allard +7
We give two examples of spiral galaxies that show non-circular gas motions in the inner kiloparsecs, from SAURON integral field spectroscopy. We use harmonic decomposition of the v…
Triaxial Orbit-based Models Of Elliptical Galaxies
Remco van den Bosch, Glenn van de Ven, Ellen Verolme +2
We have developed an orbit-based method for constructing triaxial models of elliptical galaxies, which fit their observed surface brightness and kinematics. We have tested the meth…
Dark Matter in the Central Regions of Early Type Galaxies
M. Cappellari, R. Bacon, M. Bureau +12
We investigate the well-known correlations between the dynamical mass-to-light ratio M/L and other global observables of elliptical (E) and lenticular (S0) galaxies. We construct t…
Revisiting the (V/sigma)-epsilon anisotropy diagram of early-type galaxies using integral-field kinematics
M. Cappellari, R. Bacon, M. Bureau +11
We use integral-field observation of the stellar kinematics obtained with SAURON in combination with Schwarzschild dynamical models to revisit our understanding of the classic (V/s…
The dynamical distance and intrinsic structure of the globular cluster omega Centauri
G. van de Ven, R. C. E. van den Bosch, E. K. Verolme +1
We determine the dynamical distance D, inclination i, mass-to-light ratio M/L and the intrinsic orbital structure of the globular cluster omega Cen, by fitting axisymmetric dynamic…
Radial velocities in the globular cluster omega Centauri
R. A. Reijns, P. Seitzer, R. Arnold +5
We have used the ARGUS multi-object spectrometer at the CTIO 4m Blanco telescope to obtain 2756 radial velocity measurements for 1966 individual stars in the globular cluster omega…

Glenn van de Ven, Ellen Verolme, Michele Cappellari +1
We have developed a method to construct realistic triaxial dynamical models for elliptical galaxies, allowing us to derive best-fitting parameters, such as the mass-to-light ratio…
