Star Formation Law at Sub-kpc Scale in the Elliptical Galaxy Centaurus A as Seen by ALMA

Figure 4

Relation between the surface density of molecular gas and for normal galaxies (blue squares), starburst galaxies (green triangle), and the elliptical galaxy Centaurus A (red circles). The gas surface density is derived from CO(2-1) emission. The normal and starburst galaxy samples are obtained from Kennicutt [13].
