Optomechanical design of the MUSE spectrograph structure
P SOC PHOTO-OPT INS 5492 (2004) 429-432
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
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.Parametric recovery of line-of-sight velocity distributions from absorption-line spectra of galaxies via penalized likelihood

SAURON dynamical modeling of NGC 2974
IAU SYMP (2004) 305-306
Abstract:
We present a three-integral orbit superposition Schwarschild model of NGC 2974, observed with the integral-field unit SAURON. We explore the dynamical structure of the stars and gas.SPIFFI observations of the starburst SMM J14011+0252: Already old, fat, and rich by z=2.565
