Abstract

Detailed radio observations of Mkn 509, a Seyfert type I galaxy, have revealed an extended radio feature at 6 and 20 cm at a position angle of −65° and pointing toward the northwest. It is remarkably well-aligned with the direction of polarized Hα emission, a disk of low-ionization narrow-line region and polarized optical to IR continuum indicating that both scattering and synchrotron radiation contribute to the polarized emission. A faint linear structure at 6 cm (length ≈2 kpc), almost parallel to the minor axis of the galaxy is tentatively identified as a 'jet' and needs to be confirmed with higher resolution observations. The 'jet' extends into the narrow-line region and can easily be confined by the narrow-line gas. A plausible geometry of the emission regions is presented.
