| Abstract: |
We have applied a PSF-fitting algorithm developed by John Krist(STScI) to analyze archival HST-NICMOS images of NGC 1068. We decomposed the central ∼2 arcseconds into a bright, unresolved (point) source and a ∼50 parsec diameter extended source. The point source has very red near-infrared colors, as expected for an AGN, but the extended source has colors matching those of an evolved, slightly reddened star cluster. Except for photometry, the properties of the cluster are compatible with the spectroscopic imaging results reported by Thatte et al. (1996). We consider the implications of the evolutionary stage of the cluster and present prospects of a more extended study of star clusters in Seyfert nuclei. |
