The Wide-field Infrared Survey Explorer (WISE) has scanned the entire skywith unprecedented sensitivity in four infrared bands, at 3.4, 4.6, 12, and 22micron. The WISE Point Source Catalog contains more than 560 million objects,among them hundreds of thousands of galaxies with Active Nuclei (AGN). Whiletype 1 AGN, owing to their bright and unobscured nature, are easy to detect andconstitute a rather complete and unbiased sample, their type 2 counterparts,postulated by AGN unification, are not as straightforward to identify. Matchingthe WISE catalog with known QSOs in the Sloan Digital Sky Survey we confirmprevious identification of the type 1 locus in the WISE color space. Using avery large database of the popular CLUMPY torus models, we find the colors ofthe putative type 2 counterparts, and also, for the first time, predict theirnumber vs. flux relation that can be expected to be observed in any given WISEcolor range. This will allow us to put statistically very significantconstraints on the torus parameters. Our results are a successful test of theAGN unification scheme.
