Scientific paper

We propose to carry out a NICMOS snapshot survey in F160W for a sample of 134 nearby, normal, non-barred, non edge-on, Sa and Sb spiral galaxies. The survey is a follow up of a cycle 6 WFPC2 snapshot survey and aims at investigating the core properties of spiral galaxies, their correlations with global galactic properties, and the color distribution of central point sources and multiple nuclei. The available F606W images have revealed the widespread presence of dust down to the smallest scales accessible with HST and a wide variety of nuclear morphologies, including spiral structure often reaching distances of 10 pc or less from the center. Near-IR data at HST resolution are essential for correcting for the effect of dust and will enable us to derive robust nuclear properties for the sample.
