J/AJ/113/2000 J/AJ/113/2000 New quasar radio detections O B Bischof R H Becker Astron. J. 113 2000 1997 1997AJ....113.2000B VII/188 : Quasars and Active Galactic Nuclei (7th Ed.) (Veron+ 1996) QSOs Radio sources Using the NVSS radio catalog, we have searched for radio emission from 4079 quasars taken from the 1996 version of the Veron-Cetty & Veron [ESO Scientific Report No.X (1996, Cat. <VII/188>)] quasar catalog. The comparison resulted in the positive detection of radio emission from 799 quasars of these, 168 are new radio detections. Examination of the radio luminosities shows a dramatic increase in 9 the fraction of radio-loud quasars from the current epoch to z=0.5 and a gradual decline beyond z=1.0. Inspection of the radio-loud fraction as a function of MB shows little dependence fainter than M_B_=-29.5.
