A near-infrared polarized bipolar cone in the Circinus galaxy
(2000)
We present near–infrared broad–band polarization images of the nuclear regions of the Circinus galaxy in the J, H and K bands. For the first time the south–eastern reflection cone is detected in polarized light, which is ...
Constraints on the nuclear emission of the Circinus galaxy : optical and near-IR spectropolarimetry
(2000)
We present optical and, for the first time, K-band spectropolarimetry of the nuclear region of the Circinus galaxy. In the optical we confirm the previous discovery of polarized broad Hα. We have not detected polarized ...
Polarized broad HeI and Paschen lines in NGC 1068
(1999)
We present J-band spectropolarimetry of NGC 1068. We observe polarized broad Pa β and, for the first time, polarized broad Pa γ and HeI. Assuming electron scattering as the polarization mechanism, the polarized broad lines ...
Searching for the hidden broad-line region in Centaurus A
(1999)
We present the first near-infrared (K-band) spectropolarimetric observations of the nuclear region of Centaurus A. Although the data are of high signal-to-noise ratio, polarized broad Brγ is not detected and we place a 3σ ...
