The rotating wind of the quasar PG 1700+518
(Nature Publishing Group, 2008-02-27)
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 accretion of gas1,2. Winds launched from ...
A spectropolarimetric atlas of Seyfert 1 galaxies
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2002-09-27)
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 these, the optical emission from the active ...
Highly polarized structures in the near-nuclear regions of Cygnus A: Intrinsic anisotropy within the cones?
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-04)
We present near-IR imaging polarimetry observations of the nucleus of Cygnus A, taken with the NICMOS camera of the HST at a wavelength of 2.0µm. These maps reveal a highly collimated region of polarized emission straddling ...
