Abstract We propose to search for evidence of recent star formation around active galactic nuclei. FOS and GHRS ultraviolet spectra of all Seyfert1/2 galaxies and LINER's in the HST Archive will be extracted. In addition, we will retrieve all available WFPC and FOC images. The data will be used to study the UV continuum and spectral lines in and near the Seyfert nucleus. In particular, we will search for signatures of stellar absorption lines of Si IV, C IV, and N V to constrain the population of hot stars. The stellar-wind absorptions have blueshifts of the order of 1000 - 2000\ km\ s^-1. The method will be calibrated with the Seyfert2 prototype NGC1068 for which a plethora of material is available in the Archive. FOS and GHRS spectra of NGC1068 will allow us to evaluate the relative contribution of circumnuclear star formation to the nuclear spectrum. Evolutionary synthesis models of starburst regions will be used to investigate if and how the properties of the NGC1068 starburst can be generalized and applied to other Seyfert galaxies. We will use the results of the proposed study to address the universality of massive star formation in active galaxies. ------------------------------------------------------------------------------------ Observations Description ------------------------ Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 5804( 0) - 07/18/95 18:02 - [ 2] Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_Address Ship Via: UPS Email: , ------------------------------------------------------------------------------------ 5804( 0) - 07/18/95 18:02 - [ 3] Summary Form for Proposal 5804 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Proposal Category AR ------------------------------------------------------------------------------------------------------------------------------------ Scientific Category AGN ------------------------------------------------------------------------------------------------------------------------------------
