EXOSAT observations of a broad absorption-line quasar : PHL 5200.
Abstract
Results are presented of broadband (0.05-10 keV) observations of the high-redshift quasar PHL 5200 using the EXOSAT Observatory. In observations of the 45-arcmin (FWHM) region centered on this broad-absorption-line quasar, performed with the medium-energy (ME) and low-energy (LE) experiments, X-ray emission has been detected in the 2-6 keV energy band; no sources were detected in the 0.05-2.0-keV energy band. These observations have been used to suggest that the quasar rather than a cluster of galaxies or a star in the ME field is the optical counterpart of the 2-6-keV X-ray source.
