The SAURON project – I. The panoramic integral-field spectrograph
A new integral-field spectrograph, SAURON, is described. It is based on the TIGER principle, and uses a lenslet array. SAURON has a large field of view and high throughput, and allows simultaneous sky subtraction. Its design is optimized for studies of the stellar kinematics, gas kinematics, and line-strength distributions of nearby earlytype galaxies. The instrument design and specifications a...
متن کاملSauron: Integral-field Spectroscopy of Galaxies
We present the first results from a new and unique integral-field spectrograph, SAURON. Based upon the TIGER concept, SAURON uses a lens array to obtain two-dimensional spectroscopy with complete spatial coverage over a field of 33 ′′ × 41 ′′ in low-resolution mode (0. ′′ 94 lenslets) and of 9 ′′ × 11 ′′ in high-resolution mode (0. ′′ 26 lenslets). The spectra cover the wavelengths from 4800Å t...
متن کاملThe SAURON project - V. Integral-field emission-line kinematics of 48 elliptical and lenticular galaxies
We present the emission-line fluxes and kinematics of 48 representative elliptical and lenticular galaxies obtained with our custom-built integral-field spectrograph SAURON operating on the William Herschel Telescope. Hβ, [O III]λλ4959,5007, and [N I]λλ5198,5200 emission lines were measured using a new procedure that simultaneously fits both the stellar spectrum and the emission lines. Using th...
متن کاملThe SAURON project - VII . Integral - field absorption and emission - line kinematics of 24 spiral galaxy bulges
We present observations of the stellar and gas kinematics for a representative sample of 24 Sa galaxies obtained with our custom-built integral-field spectrograph SAURON operating on the William Herschel Telescope. The data have been homogeneously reduced and analysed by means of a dedicated pipeline. All resulting datacubes were spatially binned to a minimum mean signal-to-noise ratio of 60 pe...
متن کاملKMOS: an infrared multi-integral field spectrograph for the VLT
We describe a proposed 2 generation instrument (KMOS) for the ESO VLT which will deliver a unique multiple deployable integral field capability in the near-infrared (1-2.5ìm). The science drivers for such an instrument are presented and linked to the functional specification. The overall instrument concept is discussed in the context of two proposed solutions for delivering a deployable integra...
