An atlas of mid-infrared dust emission in spiral galaxies

Abstract

We present maps of dust emission at 7 μm and 15 μm/7 μm intensity ratios of selected regions in 43 spiral galaxies observed with ISOCAM. This atlas is a complement to studies based on these observations, dealing with star formation in centers of barred galaxies and in spiral disks. It is accompanied by a detailed description of data reduction and an inventory of generic morphological properties in groups defined according to bar strength and HI gas content.
