The rotating wind of the quasar PG 1700+518
S. Young, D. J. Axon, A. Robinson +2
It is now widely accepted that most galaxies undergo an active phase, during which a central super-massive black hole generates vast radiant luminosities through the gravitational…
Gemini Mid-IR Polarimetry of NGC1068: Polarized Structures Around the Nucleus
C. Packham, S. Young, R. S. Fisher +7
We present diffraction limited, 10um imaging polarimetry data for the central regions of the archetypal Seyfert AGN, NGC1068. The position angle of polarization is consistent with…
Equatorial scattering and the structure of the broad-line region in Seyfert nuclei: evidence for a rotating disc
J. E. Smith, A. Robinson, S. Young +2
We present detailed scattering models confirming that distinctive variations in polarization across the broad Halpha line, which are observed in a significant fraction of Seyfert 1…
Seyferts on the edge: polar scattering and orientation-dependent polarization in Seyfert 1 nuclei
J. E. Smith, A. Robinson, D. M. Alexander +3
We have identified 12 Seyfert 1 galaxies that exhibit optical polarization spectra similar to those of Seyfert 2 galaxies in which polarized broad-lines are detected. We present ne…
A Spectropolarimetric Atlas of Seyfert 1 Galaxies
J. E. Smith, S. Young, A. Robinson +4
We present optical spectropolarimetry of the nuclei of 36 Seyfert 1 galaxies, obtained with the William Herschel and the Anglo-Australian Telescopes from 1996 to 1999. In 20 of the…
HST infrared imaging polarimetry of Centaurus A: implications for the unified scheme and the existence of a mis-directed BL Lac nucleus
A. Capetti, E. J. Schreier, D. J. Axon +6
We report results from HST/NICMOS 2 micron imaging polarimetry of the central region of Centaurus A. In the vicinity of the nucleus we observe a complex polarization structure whic…
