The Circinus Galaxy



Color composite ATCA HI Spitzer 8 micron Spitzer 3.6 micron

The Circinus Galaxy as seen at different wavelengths. The three single-color panels show the ATCA HI gas distribution at an angular resolution of 15 arcsec (only the inner disk is shown here), the Spitzer 8 micron image (PAH emission + stars) and the Spitzer 3.6 micron image (stars).

Reference: For, Koribalski & Jarrett 2012.

The overall HI gas distribution of the Circinus Galaxy is much larger, see here.
