Space telescope Imaging Spectrograph
We acquired spectra of 24 LMC PNe in the 1150–3000 Å range in order to determine carbon and other ionic abundances. The sample more than doubles the number of LMC PNe with good quality UV spectra in this wavelength range, and whose optical images are available in the HST archive. The Space Telescope Imaging Spectrograph was used with a very large aperture to obtain virtually slit-less spectra, ...
متن کاملMeasurement of Cosmic Shear with the Space Telescope Imaging Spectrograph
Weak lensing by large-scale structure allows a direct measure of the dark matter distribution. We have used parallel images taken with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope to measure weak lensing, or cosmic shear. We measure the shapes of 26036 galaxies in 1292 STIS fields and measure the shear variance at a scale of 0.51 arcminutes. The charge transfer ...
متن کاملA Multi-object Double Spectrograph for the Large Binocular Telescope
We are building a Multi-Object Double Spectrograph for the Large Binocular Telescope. The main themes of our planned research with the instrument are the formation and evolution of galaxies and their nuclei and the evolution of large-scale structure in the universe, although we expect that the spectrograph will be used for many other varieties of programs as well. The science goals for the inst...
متن کاملThe Hobby-Eberly Telescope Low Resolution Spectrograph: optical design
The Hobby Eberly Telescope (HET) is a revolutionary large telescope of 9.2 meter aperture, which is currently undergoing commissioning at McDonald Observatory. First light was obtained on December 11, 1996. Scientific operations are expected in 1998. The Low Resolution Spectrograph (LRS, a collaboration between the University of Texas at Austin, the Instituto de Astronomía de la Universidad Nac...
متن کاملTwo spectrograph control displays for the W.M. Keck Telescope
In the next section we discuss the advantages of depicting graphically the spectrograph light path. In section four we discuss our philosophy regarding user interaction. In section five we compare two approaches for working within limited screen space. Section six describes the stand alone simulation mode used for training and debugging. Finally, in section seven we discuss the development tool...
