    CCD photometry of the M87 jet
    CCD photometry of the M87 jet in the Thuan-Gunn r and g filters is presented. Accurate elliptical models of the underlying stellar emission were subtracted from...

    CCD surface photometry of the low-luminosity radio galaxies containing radio jets B2 0034 + 25 and B2 0206 + 35
    CCD imaging of low-luminosity radio galaxies to detect the optical counterparts of radio jets is described in terms of the surface-photometry procedure and the...

    Classification and abundance of extremely red galaxies with R-J≥5
    This thesis investigates the abundance and properties of extremely red galaxies (EROs). Although the existence of such conspicuous galaxies has been known for...

    Colors 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...

    Counterrotating 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...

    Do 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...

    Early-type galaxies: application of a new spectrophotometric population synthesis model.
    The authors have applied a new spectrophotometric stellar population synthesis model, designed to study early-type galaxies (Vazdekis, Casuso et al. 1995), to...
