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 ...
Observations and a model for the infrared continuum of Centaurus A
(1999)
We present ISOPHOT S, ISOSWS and 8 to 13 mi- cron ground based observations of Centaurus A that show prominent PAH and silicate features. These and other data are used to construct a model for the infrared continuum. We ...
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 ...
