Radio Observations of 4079 Quasars
O. B. Bischof, Robert H. Becker
Using the NVSS radio catalog, we have searched for radio emission
from 4079 quasars taken from the 1996 version of the Veron-Cetty
and Veron (1996) 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 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 M_B shows
little dependence fainter than M_B=-29.5.
