High Accuracy Imaging Polarimetry with NICMOS
D. Batcheldor, G. Schneider, D. C. Hines +5
The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2-1.5%. To better quantify an…
Weighing black holes from zero to high redshift
A. Marconi, D. Axon, R. Maiolino +4
The application of the virial theorem provides a tool to estimate supermassive black hole (BH) masses in large samples of active galactic nuclei (AGN) with broad emission lines at…
Resolving the BLR in NGC 3783
P. Lira, M. Kishimoto, A. Robinson +5
We present results from very high signal-to-noise spectropolarimetric observations of the Seyfert 1 galaxy NGC 3783. Position Angle (PA) changes across the Balmer lines show that t…
Spectropolarimetry and the Geometry of Type 1 Seyfert Nuclei
Andy Robinson, David J. Axon, James E. Smith
We describe the results of a detailed study of the polarization properties of the broad H-alpha emission line in Type 1 Seyfert nuclei. Our analysis of these data points to a model…
