Free format text (please update) We have completed an extensive survey which revealed that Seyfert 1 nuclei are much more common than previously thought in nearby galaxies. Most of the nuclei have broad HAlpha luminosities ranging from 10 to 1000 times fainter than those of classical Seyfert 1 nuclei. These ``dwarf'' Seyferts populate the faint end of the local AGN luminosity function and hold important clues to the evolution of the entire AGN population. They also may contribute to the X-ray background. Our survey has identified a large, statistically significant sample of these objects for the first time, and we are conducting a program to study their properties systematically. Using WFPC2, we propose to obtain UV (F218W) and visual (F547M) continuum images to study the UV light distribution of a subsample of 24 dwarf Seyfert 1 nuclei. The UV properties of these sources, as well as their relationship to those of Seyfert 1 nuclei of higher luminosity or to those of narrow- lined AGNs, are largely unknown. We will combine the UV fluxes with archival ROSAT data to investigate the dependence of the UV--X-ray spectral energy distribution on luminosity. Bright UV sources will become prime targets for future spectroscopic observations with HST. As by-products of this study, we will publish UV surface photometry of the observed galaxies, and we will identify interesting morphological features (e.g., dust lanes, blue stars, HII regions). Moreover, we will be able to recognize compact cores that may be produced by massive central black holes. Questions ! Free format text (please update) Observing_Description: We will use the WFPC2 PC and the F218W filter to obtain broadband UV images of 24 dwarf Seyfert 1 nuclei chosen from our ground-based survey (Ho et al. 1996b). In addition, visual (F547M) images will be taken for 14 objects; either F547M or F606W images of the other 10 are already available in the HST archive (see Table 1). The original complete sample contains 48 objects; we eliminated 24 which already have suitable UV and visual images listed in the PAEC catalog. We will incorporate the archival data into our analysis of the entire sample as part of the archival Cycle 6 project, ``An Archival Study of Nearby Low-Luminosity Active Galactic Nuclei'' (PI: Filippenko; Co-Is: Ho, Sargent, Barth). To avoid undersampling the cores of point sources, the nucleus will be placed on the PC chip. Two exposures, of duration 1200 sec each (CR-SPLIT), will be taken with the F218W filter, and two 180-sec exposures will be taken with the F547M filter. Our choice to use WFPC2 (with the F218W filter) instead of the FOC/96 (with the F220W filter) was based on several considerations. Because of the low dynamic range of the FOC/96, most bright point sources will be saturated. The field-of-view of the FOC is very limited (maximum 14 arcsec x 14 arcsec) and restricts our ability to do detailed surface photometry over large areas or to study the circumnuclear environment of the galaxies. Adopting parameters anticipated for the proposed targets, we made detailed simulations to compare the UV sensitivity of the two instrument setups. We find that the WFPC2 is only ~ 50\% lower in UV sensitivity relative to the FOC/96. Based on previous HST observations of similar objects (e.g., Maoz et al. 1995), the expected flux level is ~ 10^-15 erg/s/cm^2/Ang. We estimate that the count rate per 0.046" x 0.046" pixel will be 0.17 per second in the F218W filter for extended (1") sources, thus yielding a S/N ~ 20 for the two combined 1200- second exposures. Point-like nuclei will be even brighter in the central few pixels; they will be easily detected, and good photometry will be obtained. The F547M observation will require only 6 minutes to achieve S/N = 40 per pixel. The F218W filter (as well as all other UV filters, except for the very inefficient Woods filter) is known to suffer from red leak. For early-type stars, this can amount to 30--40\% of the total light blueward of ~ 3000 Angstrom. We will estimate the amount of contamination in the UV images using the visual images. The latter are additionally critical for evaluating the origin of the UV light, if detected. At the typical distances and absolute magnitudes of our program galaxies, expected core radii based on observed core parameter relations are typically 0.2", and many are expected to be < 0.1". Therefore, since the profiles are likely to be cuspy anyway, we need to have a method for determining which cores are probable AGNs (bright in the UV relative to the visual) --- the V-band cusps could just be star clusters. Measurements of color gradients in the nuclear regions will also help us eliminate cases in which dust rings or stellar population gradients produce unresolved (or nearly unresolved) nuclei.
