Abstract Try to understand the energies of normal galactic nuclei. Are the main sources of ionizing radiation nonthermal, or due to a blue stellar population? High spatial resolution of ST is essential to this problem; FOS spectra can distinguish between a population of hot young stars or HB stars. Use the 0.3" aperture at any central point sources and off nucleus at the appropriate spot determined from WFPC data. Choose this spot within 1", along the major axis in accord with the techniques of FOS program 24, "Dynamics near Cores of Normal Galaxies." ------------------------------------------------------------------------------------ 8.

Ford SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 3. Description of proposed observations. Cycle 9: 901-911 ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The SV prerequisite programs for all FOS observations in this program are: Prop ID 2195 FOS Target Acquisition Tests - All observations Prop ID 1317 Int./Ext. Wavelength Offsets - 1st target Prop ID 1318 Spectral Flat Fields - 1st target Prop ID 1320 Absolute Spectrophotometry - 1st visit of bright targets All WF/PC imaging with a center wavelength blueward of 5000 Angstroms requires UV flood ------------------------------------------------------------------------------------ 12. This program does not become a viable scientific investigation until observations are complete on at least 5 of the 7 targets. No data should be made public until at least 1 year after that time. ------------------------------------------------------------------------------------ 13. The purpose is to use WFPC images and FOS spectra of the central regions of galaxies to study the source of the ionizing radiation and to address the question of the presence of a black hole. ------------------------------------------------------------------------------------ 11.
