    A counterrotating core in the merger remnant candidate NGC 3656 (ARP 155)
    A study is presented of the internal velocity structure of NGC 3656, a galaxy with several morphological signatures of being in an advanced merger stage...

    A new framework for investigating the evolution of Early Type Galaxies
    I present a detailed analysis of the scaling relations of ETGs and suggest a way to predict the evolution of the distributions of galaxies in these planes. This...

    A new SMBH mass function for the local Universe
    We present our latest measurement of the SMBH mass function at redshift zero based on detailed structural studies of 1743 galaxies extracted from the B-band...

    A stellar disk perpendicular to the radio jet in B2 0034+25
    CCD surface photometry of the radio galaxy B2 0034+25 is reported. Fourier analysis of the intensity variations along a set of closely spaced elliptical...

    Application of a new evolutionary model for stellar populations to photometric maps of M32
    A cyclical approximation of the evolutionary synthesis of stellar populations has been developed into a general solution for the mass and time-dependence of the...

    Astronomical observations and synthesis of ellipsoidal triaxial structures. I. Geometrical considerations.
    Isophotal analyses developed in recent years (CCD images and numerical mapping techniques) have revealed that triaxial structures are frequently present in...

    BL Lac nuclei in elliptical galaxies
    Orientation effects are believed to be important in sources which harbor relativistic jets in their nuclei. BL Lac type objects are interpreted as a type of...

    CCD photometry of axisymmetric and non-axisymmetric Galactic bulges in the I-band
    The paper presents a set of CCD images of four Galactic bulges, taken in the I photometric band under very good imaging conditions, with the Taurus camera on...

    CCD photometry of Seyfert galaxies
    Morphology and elliptically averaged luminosity profiles have been derived from CCD surface photometry of thirteen Seyfert galaxies. Apparent V and I magnitudes...
