Conference Paper: Quasar Spectroscopy with FLAIR

TitleQuasar Spectroscopy with FLAIR
Authors
Issue Date1-Jul-1995
Abstract

We demonstrate that the multi-object fibre-spectroscopy system ‘FLAIR’ on the UKST can be used to observe efficiently and effectively the brighter (B < 18.5) high-grade quasar candidates identified from UKST low-dispersion objective-prism plates. The quasar candidates were selected objectively by the application of AQD (automatic quasar detection) to prism plates that have been digitised using the COSMOS measuring machine. Thirteen high-grade quasar candidates with B ≤ 18.5 from a prism plate of ESO/SERC survey field 296 were observed with a 35-fibre version of FLAIR. From a total observing time of only 3 hours at a resolution of 8.4 Å/pixel six candidates were confirmed as quasars and four were identified as stars. The planned upgrade to a thinned, back-illuminated CCD in 1994 should yield a 3-fold increase in sensitivity and further enhance the capabilities of FLAIR for performing useful spectroscopic observations of quasars of moderate faintness over large areas of sky.
