  Spitzer mid-infrared images of the dusty warped disk in the galaxy Centaurus
A show a parallelogram-shaped structure. We successfully model the observed
mid-infrared morphology by integrating the light from an emitting, thin, and
warped disk, similar to that inferred from previous kinematic studies. The
models with the best match to the morphology lack dust emission within the
inner 0.1 to 0.8 kpc, suggesting that energetic processes near the nucleus have
disturbed the inner molecular disk, creating a gap in the molecular gas
distribution.
