Scientific paper

We have obtained 10 microns images and spectra of the starburst/Seyfert hybrid galaxy NGC 7469 using the new instrument SpectroCam-10 on the Hale 5 m telescope. Our maps, with spatial resolution of 0.5'', show the same 3'' diameter starburst ring around the unresolved nucleus as a VLA 6 cm map of this galaxy made with similar resolution by Wilson et al. (1991, ApJ, 381, 79). A long-slit, low resolution spectrum shows a weak, broad 11.7 microns PAH feature in the nucleus.
