Separating stars from galaxies with AKARI data

Date: 30 March 2010
Satellite: AKARI
Copyright: From Pollo et al., 2010

The AKARI catalogues cover the wavelengths 9, 18, 65, 90, 140 and 160 micrometres. These different wavelengths can be used to separate the various generic classes of objects, such as stars (blue) and galaxies (red), in what is called colour-colour space. This allows astronomers to select samples of the various classes of objects that they wish to study.
