| Abstract: |
The Unification Model proposes that various types of AGN (e.g., QSO vs. Hyperluminous Infrared Galaxy) are fundamentally similar in nature, but appear to have diverse properties because they are viewed at different angles. These aspect angles accentuate or de-emphasize emission at various wavelengths and from various regions near the central engine. The SIRTF AGN SED program is aimed to understanding the far-IR properties of Luminous AGN and will provide the SIRTF deep surveys with templates for classifying the newly discovered objects. We have selected a number of different AGN catalogs based on different observational properties, e.g., x-ray brightness, high frequency radio brightness, infrared emission, etc. From the complete AGN catalogs, we have drawn the most luminous examples (10-20 objects) at redshifts of z lower than 0.4. The use of previously well defined samples and the z lower than 0.4 redshift limit aids completeness and ensures access to large existing databases and high resolution imaging. We supplement the core sample with two small samples of AGNs at high redshift to probe evolutionary trends. This comparison will be particularly important for evaluating the effectiveness of our low-z SEDs as templates for identifying very high redshift AGNs. |
