Abstract
We present speckle masking observations of the core of the Seyfert plus
circumnuclear starburst hybrid galaxy NGC7469. High-resolution images
were obtained in three different wavelength bands. The images show a
ring-shaped emission region with a radius of about 1".3 (~ 400 pc at a
distance of 65 Mpc) consisting of about a dozen individual cloud-like
features. Near the center of the ring we find a bright unresolved
source superimposed on an extended and elongated structure extending
about +/- 0".4 towards the PAs 50deg and 230deg.
2) Speckle masking observations of NGC 1068 and NGC
7469
