On the Anomalous Silicate Emission Features of AGNs: A Possible Interpretation Based on Porous Dust [PDF]

open access: yes, 2008
The recent Spitzer detections of the 9.7 micron Si--O silicate emission in type 1 AGNs provide support for the AGN unification scheme. The properties of the silicate dust are of key importance to understanding the physical, chemical and evolutionary properties of the obscuring dusty torus around AGNs.
