Scientific paper

We observed the mid-IR spectra for a sample of Two Micron All Sky Survey selected red AGN using the Spitzer Space Telescope. Their mid-IR spectra show a great variety. The silicate features range from deep absorption to significant emission. The silicate features in general agree with the optical classification of the sources. The sources with the deepest silicate absorption are those that show Hα emission but not Hβ emission in their optical spectra. The average spectrum of the whole sample is flatter than for classical AGN, indicating that if extinction is the reason for our sources' red color, it is most likely due to warm dust.
