Abstract:
Images of resolved radio sources in the Palomar Bright Quasar Survey
are presented with an angular resolution of 0.5 and 18arcsec. The
observed structure of some well resolved radio quiet quasars and AGN's
show large scale linear structures or unresolved central cores similar
to radio loud objects in the BQS sample as well as the more luminous
radio selected quasars. We suggest that at least some of these less
luminous radio quiet objects may contain compact central engines
characteristic of radio loud quasars and radio galaxies.
