HIGH-RESOLUTION RADIO OBSERVATIONS OF INTERMEDIATE REDSHIFT QUASARS AND RADIO GALAXIES

Autor: BOGERS, WJ, HES, R, BARTHEL, PD, ZENSUS, JA

Publikováno v: Astronomy & astrophysics supplement series, 105(1), 91-113

We present radio maps of a collection of intermediate redshift quasars and radio galaxies mostly taken from the 3C and 4C catalogues. The sources were observed with the Very Large Array (VLA) at one or more of the following frequencies: 15 GHz, 8.4 G
