Abstract
Surface photometry data obtained with the Faint Object Camera of the H ubble Space Telescope in the cores of ten galaxies is presented. The m ajor results are: (i) none of the galaxies show truly ''isothermal'' c ores, (ii) galaxies with nuclear activity show very similar light prof iles, (iii) all objects show central mass densities > 10(3) M . pc-3, (iv) four of the galaxies (M87, NGC 3862, NGC 4594, NGC 6251) show evi dence for exceptional nuclear mass concentrations.
