PublicationColors and color gradients in bulges of galaxies
We have obtained surface photometry in U, B, R, and I for a complete optically selected sample of 45 early-type spiral galaxies, to investigate the colors and...

PublicationCounterrotating cores in elliptical galaxies
The dynamics of the merger between a high- and a low-elliptical galaxy was studied to understand how kinematically peculiar cores in elliptical galaxies might...

PublicationDo all bright elliptical galaxies have active nuclei?
The evidence is noted that (1) a flux density limited complete sample of X-ray emitting BL Lac type sources is now available from Schwartz and Ku (1983), that...
