The Multiwavelength Quasar Survey. II. Quasars in the Coma cluster. Chen Y., He X.-T., Wu J.-H., Li Q.-K., Green R.F., Voges W. <Astron. J. 123, 578 (2002)> =2002AJ....123..578C
ADC_Keywords: QSOs ; Galaxies, Seyfert ; BL Lac objects ; X-ray sources Keywords: galaxies: active - galaxies: clusters: individual (Coma) - quasars: general Abstract: This is the second paper of the series about our Multiwavelength Quasar Survey. We present the observational results for the X-ray candidates in the field of the Coma Cluster. Nine new X-ray active galactic nuclei are discovered. File Summary:
