... Dust in Nuclei of Galactic Bulges . ... WFPC2 of 20 nuclei of nearby galactic bulges of types S0-Sbc. ... Bulges of spiral galaxies are generally seen as small elliptical galaxies in the center of a large spiral. ... Here we show first results of a color study of the centers of galactic bulges. ... With these three bands we can make the red I - H color, primarily sensitive to extinction by dust and old stellar population gradients, and the B - I color, especially sensitive to recent star formation. ...
