Description
I will present results from multi-frequency Very Long Baseline
Interferometry (VLBI) observations of Seyfert galaxies. These observations
are probing the parsec-scale nuclear structures in these spiral galaxies. They
are revealing the presence of a variety of weak radio outflows in these galaxies
and the tentative presence of dual radio cores which could be dual accreting
supermassive black holes, in one of them. The properties of some of the weak
outflows are more consistent with being bases of coronal winds rather than
synchrotron self-absorbed bases of relativistic jets. I will discuss the different
parsec-scale radio structures that we observe in these low luminosity AGN.
