The Origin of the Silicate Emission Features in the Seyfert 2 Galaxy, NGC 2110
R. E. Mason, N. A. Levenson, Y. Shi +5
The unified model of active galactic nuclei (AGN) predicts silicate emission features at 10 and 18 microns in type 1 AGN, and such features have now been observed in objects rangin…
The Spatial Variation of the 3micron Dust Features in Circinus
M. D. Colling, P. F. Roche, R. E. Mason
We report spatially-resolved variations in the 3.4micron hydrocarbon absorption feature and the 3.3micron polycyclic aromatic hydrocarbon (PAH) emission band in the Circinus galaxy…
Gemini Imaging of Mid-IR Emission from the Nuclear Region of Centaurus A
James T. Radomski, Christopher Packham, N. A. Levenson +7
We present high spatial resolution mid-IR images of the nuclear region of NGC 5128 (Centaurus A). Images were obtained at 8.8 micron, N-band (10.4 micron), and 18.3 micron using th…
The Mid-Infrared Emission of M87
E. S. Perlman, R. E. Mason, Christopher Packham +6
We discuss Subaru and Spitzer Space Telescope imaging and spectroscopy of M87 in the mid-infrared from 5-35 um. These observations allow us to investigate mid-IR emission mechanism…
Spectropolarimetry of the 3.4 micron absorption feature in NGC 1068
R. E. Mason, G. S. Wright, A. Adamson +1
In order to test the silicate-core/organic-mantle model of galactic interstellar dust, we have performed spectropolarimetry of the 3.4 micron C-H bond stretch that is characteristi…
