Abstract
ISOCAM maps of the Seyfert 1 SO galaxy NGC 3998 between 4.5 mu m and 1 5 mu m detect both extended emission from the bulge stars and strong p oint source emission from the nucleus. The inner regions of NGC 3998 a ppear to contain a few thousand solar masses of warm (similar to 200 K ) dust, probably associated with the AGN.
