The extended mid-infrared structure of the circinus galaxy

Abstract:

We present subarcsecond resolution mid-IR images of the Circinus galaxy at 8.74 and 18.33 μm. We resolve extended emission at both wavelengths, extending ∼2″ from each side of the nucleus in an approximate east-west direction. These extensions are spatially coincident with previously detected compact (∼30 pc) V-shaped [O III] emission extending northwest of the nucleus as well as countercone [Si vi] emission, emission at these wavelengths interpreted as delineating the interface between inflo...
