Fig. 4


Star formation rate density maps, based on Hα + 24 μm (left), NUV + 24 μm (middle), and FUV + 24 μm (right), at the Spitzer 24 μm (~5′′) resolution. The Hα + 24 μm derived SFRD values in this image have been multiplied by a factor two for visualization purposes. The galactic nucleus and larger radii have been masked. The radius of the circumnuclear ring and the locations of the inflow points are indicated with a dashed circle and stars, respectively. The Spitzer 24 μm beam of ~5′′  is indicated in the top left corner of each subpanel.
