Principal Investigator Institution Country Telephone Philippe Crane EUROPEAN SOUTHERN OBSERVATOR GERMANY, W (49-89)320-06- ASTRONOMER-PHYSICIST ------------------------------------------------------------------------------------ 7. Abstract The high resolution of the FOC f/96 imaging mode will be used to study the nuclear regions of several nearby spiral galaxies. A first image in the UV continuum will be used to see if there is a nuclear condensation which would merit further study either spectroscopically or at a higher spatial resolution. The major objective is to discover heretofore unknown phenomena in the nuclei on physical scales which cannot be reached from the ground. ------------------------------------------------------------------------------------ 8.

Description of proposed observations. Two straightforward exposures are requested. ------------------------------------------------------------------------------------ 13. Continuum images with the FOC f/96 camera will be used to select object for further study with either the FOC f/48 spectrograph or the f/288 camera. The main objective is to search for phenomena on physical scales which have not been studied from the ground. ------------------------------------------------------------------------------------ 11.
