Infrared views of Centaurus A
Presenter: Alice Quillen (University of Rochester)
Abstract: Spitzer Space Telescope spectroscopy and imaging of Centaurus A have revealed in exquisite detail the dusty warped disk as well as some new surprises. I will report on the discovery of a 500 pc bipolar warm dust shell. A resolved ionization cone is seen for the first time in infrared high ionization emission lines near the jet axis.
