A SAURON look at galaxy bulges

ASTRON NACHR 325:2 (2004) 92-95

Authors:

J Falcon-Barroso, R Bacon, M Bureau, M Cappellari, RL Davies, E Emsellem, D Krajnovic, H Kuntschner, R McDermid, RF Peletier, PT de Zeeuw

Abstract:

Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with state-of-the-art integral field spectrographs, such as SAURON, indicate that the situation is much more complex, and allow us to investigate phenomena such as triaxiality, kinematic decoupling and population substructure, and to study their connection to current formation and evolution scenarios for bulges of early-type galaxies. We present the examples of two SO bulges from galaxies in our sample of nearby galaxies: one that shows all the properties expected from classical bulges (NGC 5866), and another case that presents kinematic features appropriate for barred disk galaxies (NGC 7332).

Data reduction software for the VLT integral field spectrometer SPIFFI

ASTR SOC P 314 (2004) 380-383

Authors:

J Schreiber, F Eisenhauer, M Tecza, R Abuter, M Horrobin, N Thatte

Abstract:

A data reduction software package is developed to reduce data of the near-IR integral field spectrometer SPIFFI built at MPE. The basic data reduction routines are coded in ANSI C. The high level scripting language Python is used to connect the C-routines allowing fast prototyping. Several Python scripts are written to produce the needed calibration data and to generate the final result, a wavelength calibrated data cube with the instrumental signatures removed.

Design study for the KMOS spectrograph module

P SOC PHOTO-OPT INS 5492 (2004) 1395-1402

Authors:

M Tecza, N Thatte, I Lewis, J Lynn, W Lau, S Yang, I Tosh, M Wells

Abstract:

We present the results of a design study for the spectrograph module for KMOS - a cryogenic near-infrared multi-object spectrograph being developed as a second generation instrument for the VLT by a consortium of UK and German institutes. KMOS will consist of 24 deployable integral field units feeding three identical spectrograph units via image slicers. The spectrographs are designed to provide a resolving power greater than 3000, so as to provide adequate OH avoidance, whilst covering one of the J, H or K bands within a single exposure. We present the opto-mechanical layout of the spectrographs, together with an analysis of the impact of the image quality (and PSF uniformity) on the accuracy of sky background subtraction within each IFU's field of view.
