Display session, Monday, January 13
Hubble Space Telescope imaging polarimetry of the Seyfert 2 galaxy Markarian 463 E has revealed the location of an obscured Seyfert 1 nucleus. Curiously, the Seyfert 1 is not co-spatial with the optically bright Seyfert 2, but is located 1\arcsec (\sim 1 kpc) to the south, at the tip of what was previously thought to be an optical jet. The high spatial resolution broad-band UV imaging achieved with the Faint Object Camera reveals a distinct cone of highly polarized (13 \pm 3 %) light fanning northward from the obscured nucleus. The magnetic polarization vectors point at the cone's apex, indicating that te wedge of illuminated material (opening angle \sim 70\(^\circ\) is the scattering mirror that allows us to see the Seyfert 1 core.
