Scientific paper

A previous work by Higdon & Wallin (2003 ApJ, 535, 281: HW) has demonstrated by means of numerical simulations that the optical jets detected in NGC 1097 are consistent with having been formed by a minor-merger. However, this work neglected a significant bar component in the disk which could affect this conclusion. In this work we reproduce the results of HW and then continue further by including a bar component in the disk estimated from K-band observations. Through additional simulations we investigate the overall effect on the jets and whether inclusion of the bar strengthens or weakens support for the minor-merger interpretation.
