Nature and properties of pc scale jets in FR0
The local radio-loud AGN population is dominated by compact sources named FR0s. These sources show nuclear and host properties similar to FRI, but are characterized by a paucity of extended radio emission. We recently studied a sub-sample of FR0s with JVLA and EVN at 1.6 GHz. Most of unresolved sources in JVLA high resolution images are resolved in EVN images showing a complex structure, mostly symmetric with respect to a possible central core. This result suggests an instability in pc scale FR0 jets, unable to grow, possibly related to a slow jet velocity. Moreover the source flux density in EVN images is a small fraction of the source flux density measured in high resolution JVLA images at the same frequency. Parsec scale jets are disrupted in a diffuse structure on a scale between JVLA A-configuration and EVN. We propose here to observe 6 key sources with EVN + e-Merlin at 6 cm to obtain at the same time a high resolution image of the jet starting region to estimate the jet velocity and properties, and a map able to show how and why jets stop and die.
