Abstract The complex nuclear regions of a few typical galaxies will be investigated in order to get the structure both in the continuum and in the light of relevant emission lines with the highest possible resolution. The following objects have been selected. NGC 1365 is a case of active nuclear region in a barred spiral galaxy, which contains optical hot spots and a number of compact radio sources. In NGC 4278, massive hot stars, possibly formed from the gas accumulated in the center, will be searched while mapping the distribution of the ionized gas. NGC 5194 displays in an especially favorable fashion the different manifestations of the energy flow in an active galaxy. The radio elliptical 3C285 exhibits a twisting of isophotes all the way to the center. ------------------------------------------------------------------------------------ 8.

Disney UNIVERSITY COLLEGE, CARDIFF UK X ------------------------------------------------------------------------------------ 3. Description of proposed observations. NGC 1365 is observed on and off OIII lines NGC 4278 is observed with the UV filter F275W to reveal the expected young stars and with the filters F372W,F501W,F550W to trace the distribution of gas with respect to these stars. NGC 5194 is observed in UV with F275W and on and off OII lines 3C285 is observed in UV (F342W) and on OIII line ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The FOC is needed for the combination of high angular resolution and UV response. ------------------------------------------------------------------------------------ 7.
