Studying the radio emission mechanisms of radio-quiet AGN is essential for understanding the dichotomy of RQ/RL AGN, providing important insights into the properties of the accretion disks and jets of these objects, and the impact of AGN on their host galaxies and environments. Mrk110 is one of the most variable AGN in the RXTE AGN sample, and also shows moderate radio variability on timescales of days. However, the physical origin of this variability, jet or outflowing corona, is still debated. In our recent VLBA observations we found evidence for a southwest extension from the core. This proposal aims to confirm the origin of this extended structure from the jet using more sensitive EVN observations and to constrain the proper motion of the radio jet using multi-epoch VLBI observations. This study will shed light on the physics of accretion and jet formation in radio-quiet AGN, and to clarify whether Mrk110 has a central engine similar to those in radio-loud AGN.

This data is part of the archive of VLBI data maintained by JIVE on behalf of the EVN, a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa. The EVN archive itself has the DOI https://doi.org/10.17616/R3Z197
