Relativistic Jets in Radio-Weak Quasars and LINER Galaxies

We discuss radio observations of a sample of radio-weak and radio-intermediate quasars which demonstrate that - just like their radio-loud counterparts - radio-weak quasars too have relativistic jets in their nuclei. Moreover, a VLA survey of nearby LINER galaxies reveals a relatively large number of flat-spectrum radio cores. It is suggested that those cores are also best explained by moderately relativistic jets (gamma~2) produced by a central engine.
