Mid-infrared colour gradients and the colour-magnitude relation in virgo early-type galaxies

We make use of Spitzer imaging between 4 and 16 μm and near-infrared data at 2.2 μm to investigate the nature and distribution of the mid-infrared emission in a sample of early-type galaxies in the Virgo cluster. These data allow us to conclude, with some confidence, that the emission at 16 μm in pa...
