Optomechanical design of the MUSE spectrograph structure

P SOC PHOTO-OPT INS 5492 (2004) 429-432

Authors:

IJ Lewis, J Lynn, S Yang, W Lau, R Davies

Abstract:

We describe some of the design work behind the structural design of the NWSE spectrograph for the VLT1. In particular we consider the limitations on the instrument layout and the effect of its mechanical and thermal properties on the overall instrument performance.

Orbital structure of triaxial galaxies

IAU SYMP (2004) 179-180

Authors:

G van de Ven, E Verolme, M Cappellari, T de Zeeuw

Abstract:

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 and the black hole mass, and to study the orbital structure. We use triaxial theoretical Abel models to investigate the robustness of the method.
