[109.05] High Resolution 10\mum Photometry of Seyfert Galaxies in the IRAS 12\mum Sample

We have used the JPL mid-infrared camera (MIRLIN) at the Palomar 200" telescope to obtain subarcsecond, 10\mum (N-band), imaging of a large sample of Seyfert galaxies. Our sample, which consists of 95 Seyferts, was selected from the IRAS 12\mum sample which contains all galaxies brighter than 220 mJy at 12\mum.

We detected 50 of those 95 galaxies at a S/N sufficient for obtaining good photometry. Included within those 50 are 12 galaxies which do not have previously published small aperture N-band photometry. Also, all our detected sources have a dominant central source, and are consistent with being unresolved.

We intend to use this large sample to obtain statistical correlations between the near-IR (J,H,Ks) and the mid-IR properties of Seyfert 1's and Seyfert 2's. By comparing fluxes only in the IR, we significantly reduce extinction effects arising from the host galaxies, and concentrate principally on the intrinsic attributes of the central engines of these active galaxies.
