[4.07] Comparing the Position Angle of Seyfert Galaxies Radio Structures with their Host Galaxies Major Axis

H. R. Schmitt (STScI and IF-UFRGS), A. L. Kinney (STScI), T. Storchi-Bergmann (IF-UFRGS-Brasil)

We analyze the difference between the position angles of extended radio structures and host galaxy major axis of Seyfert 1 and Seyfert 2 galaxies. We find that Seyfert 1's are less likely to have extended radio structures in the host galaxy major axis, while in Seyferts 2 these structures are distributed along all directions. These results are analysed from the point of view of a model in which Seyfert 1's have their obscuring torus axis aligned preferentially along the host galaxy disk axis, and Seyfert 2's have their torus axis laying at an intermediate angle between the galaxy disk and its axis.
