Estimations of the magnetic field strength in the torus of AGN using near-infrared polarimetry
E. Lopez-Rodriguez, C. Packham, S. Young +7
An optically and geometrically thick torus obscures the central engine of Active Galactic Nuclei (AGN) from some lines of sight. From a magnetohydrodynamical framework, the torus c…
Torus and AGN properties of nearby Seyfert galaxies: Results from fitting IR spectral energy distributions and spectroscopy
Almudena Alonso-Herrero, Cristina Ramos Almeida, Rachel Mason +9
We used the CLUMPY torus models and a Bayesian approach to fit the infrared spectral energy distributions (SEDs) and ground-based high-angular resolution mid-infrared spectroscopy…
Nicmos Polarimetry of "Polar Scattered" Seyfert 1 Galaxies
D. Batcheldor, A. Robinson, D. J. Axon +5
The nuclei of Seyfert 1 galaxies exhibit a range of optical polarization characteristics that can be understood in terms of two scattering regions producing orthogonal polarization…
Spectropolarimetric evidence for a kicked supermassive black hole in the Quasar E1821+643
Andrew Robinson, Stuart Young, David J. Axon +2
We report spectropolarimetric observations of the quasar E1821+643 (z=0.297), which suggest that it may be an example of gravitational recoil due to anisotropic emission of gravita…
The Nature of the Near-IR Core Source in 3C 433
Edgar A. Ramirez, C. N. Tadhunter, D. Axon +4
We report the analysis of near-infrared imaging, polarimetric and spectroscopic observations of the powerful radio galaxy 3C433, obtained with the HST and UKIRT telescopes. The hig…
The Contribution from Scattered Light to Quasar Galaxy Hosts
S. Young, D. J. Axon, A. Robinson +1
We present models representing the scattering of quasar radiation off free electrons and dust grains in geometries that approximate the structure of quasar host galaxies. We show t…
