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 ...
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 ...
