seyfert 2 nuclei appear to live in galaxies with an ^ated rate of star formation compared with field galaxies or the host galaxies of seyfert 1 nuclei. it is not clear what causes this difference. the ^ated star formation might be associated directly with the feeding of matter into the agn, with the seyfert 2 galaxies revealing a particular stage in this process that seyfert 1s are not currently in. alternately, the ^ated star formation might arise from a common trigger -- for example, an interaction with another galaxy -- that establishes an axi- symmetric potential to feed the agn and also initiates ^ated star formation in the galaxy. again, the difference between seyfert 1s and 2s might indicate a different stage in this process. to test these possiblities, we have selected a complete sample of 17 seyfert galaxies with strong star formation and which can be well resolved by iso. we have determined the specific observations required to resolve these galaxies that are not included in the guaranteed time and we propose to obtain these data. this proposal roughly doubles the number of galaxies in our sample that iso will resolve, and will provide enough examples to determine the typical proximity of the regions of ^ated star formation to the active nuclei.

Mission Description
The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
