OASIS high-resolution integral field spectroscopy of the SAURON ellipticals and lenticulars
ASTRON NACHR 325:2 (2004) 100-103
Abstract:
We present a summary of high-spatial resolution follow-up observations of the elliptical (E) and lenticular (SO) galaxies in the SAURON survey using the OASIS integral field spectrograph. The OASIS observations explore the central 8" x 10" regions of these galaxies using a spatial sampling four times higher than SAURON, often revealing previously undiscovered features. Around 75% (31/48) of the SAURON E/SOs with central velocity dispersion greater than or similar to 120 kin s(-1) were observed with OASIS, covering well the original SAURON representative sample. We present here an overview of this follow-up survey, and some preliminary results on individual objects, including a previously unreported counter-rotating core in NGC4382; the decoupled stellar and gas velocity fields of NGC 2768; and the strong age gradient towards the centre of NGC 3489.Optomechanical design of the MUSE spectrograph structure

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.Probing the dark ages with the Square Kilometer Array
