    The First Systematic Survey of Stellar Halos in High-inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
    Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information...

    The Intrinsic Flattening of Galaxy Disks
    Highly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c/a, where c and a are, respectively, the vertical...

    The tilted old Galactic disc and the position of the Sun
    With the use of data from COBE, IRAS and the Two-micron Galactic Survey (TMGS), we examine the effect on star counts and surface brightness maps of the position...

    Through Thick and Thin: The Cosmic Evolution of Disk Scale Height
    To investigate the formation and evolution of vertical structures in disk galaxies, we measure global sech 2 scale heights, averaging thin and thick components...

    Ultramassive Black Holes in the Most Massive Galaxies: M<SUB>BH</SUB>-σ versus M<SUB>BH</SUB>-R<SUB>b</SUB>
    We investigate the nature of the relations between black hole (BH) mass (M BH) and the central velocity dispersion (σ) and, for core-Sérsic galaxies, the size...
