Gravitational Lens Candidate 1208+101: Spectroscopy
Abstract
We will obtain low resolution FOS spectra of the high-redshift quasar 1208+101 and the brightest of two candidate gravitational lens images, located about .5 arcsec from the primary image. The 0.3 arcsec circular aperture will be used to spatially resolve the images, to test the gravitational lens hypothesis. Only HST can provide sufficient spatial resolution to permit sufficiently accurate spectrophotometry of the individual images.
