The Wide Field Spectrograph ( WiFeS )
This paper describes the Wide Field Spectrograph (WiFeS) under construction at the Research School of Astronomy and Astrophysics (RSAA) of the Australian National University (ANU) for the ANU 2.3m telescope at the Siding Spring Observatory. WiFeS is a powerful integral field, double-beam, concentric, image-slicing spectrograph designed to deliver excellent thoughput, wavelength stability, spect...

متن کاملMOSFIRE: a multi-object near-infrared spectrograph and wide-field camera for the Keck Observatory
MOSFIRE, the multi-object spectrometer for infra-red exploration, is a near-IR (0.97-2.45 micron) spectrograph and imager for the Cassegrain focus of the Keck I telescope. The optical design provides imaging and multi-object spectroscopy over a field of view (FOV) of 6.14' x 6.14' with a resolving power of R~3,270 for a slit width of 0.7 arc seconds (2.9 pixels along dispersion). The detector i...
متن کاملMeasuring Dark Energy with the Wide–Field Multi–Object Spectrograph (WFMOS)⋆
Dark energy is one of the greatest scientific challenges of the 21 century. One of the key questions facing cosmologists is whether dark energy is either a breakdown of General Relativity on large scales or a new form of matter in the Universe with a negative effective pressure. This question can only be answered through a suite of different observations as a function of redshift. In this paper...
متن کاملThe 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...
