Structural variability of 3C 111 on parsec scales

Presentation duration: 15 minutes

Presenter: Christoph Grossberger

We discuss the parsec scale structural variability of the extragalactic jet 3C 111 related to a major flux density outburst in 2007. The data analyzed were taken within the scope of the MOJAVE program, which monitors a large sample of the radio brightest compact extragalactic jets with the VLBA. We compare our results with the structural variability observed during the aftermath of the last major outburst of 3C111 in 1996 (Kadler et al. 2008). The analysis is performed both by fitting Gaussian model components in the visibility domain data and by applying a hierarchical cross correlation algorithm in the image domain.
