the galactic center is the closest example of a spiral galactic nucleus, and is uniquely important both in its own right, and as a template for the study of other galactic nuclei. because it is bright, it is possible for iso to complete a basic spectral study of very weak fir lines from minor species which may hold the key to an understanding of the nature of the central engines of galaxies. because it has a relatively large angular extent, the gc is suitable even for the large beam of isos lws. the iso guaranteed time program covers only selected intervals in the fir with the fabry perot, skipping important spectral regions. in this proposal we plan full iso/lws fabry perot coverage of remaining selected, important spectral intervals pointed on sgra itself. for some aspects of our analysis it will important to incorporate the results with the iso/lws guananteed time observations on the gc. therefore, in order to maximize the science to take advantage of complementary information in the gt bands, it is our intention to make the results of our program available to the community as soon as possible (no 1 year waiting period).

Mission Description
The Infrared Space Observatory (ISO) was the worlds 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.
