    Disentangling the stellar components of the metal-poor Milky Way
    Some studies of the Milky Way halo and all studies of the thick disk populations suffer from difficulties cleanly separating out one galactic component from...

    Disentangling the Stellar Populations of Fornax Dwarf Spheroidal
    We studied the stellar populations of Fornax dwarf spheroidal galaxy using HST/WFPC2 imaging of 7 galaxy fields. Our observations reach the oldest main-sequence...
  • Publication
    Disk Galaxy Mergers and the Fundamental Plane
    We report on an ongoing study of disk galaxy merger simulations and their implications for the Fundamental Plane (FP) of elliptical galaxies.
  • Publication
    Disk Survival in the Extremely Massive Association Cygnus OB2
    Star formation in massive clusters proceeds under the influence of the intense ionizing flux emitted by OB stars. Among the massive star forming regions in our...
  • Publication
    Disk tomography and dynamics: a time-dependent study of known mid-infrared variable young stellar objects
    Most of our knowledge on young stars comes from snapshot observations: spectra and images taken at a single epoch, or at different epochs at different...

    Disky Nuclei in Early- to Intermediate-type Disk Galaxies
    Structural analysis of S0-Sbc galaxies imaged with HST at near-infrared wavelengths shows many nuclei to be flattened systems with surface brightness comparable...
  • Publication
    Dispersion in modeled abundances
    Chemical abundance data for the Galaxy show a wide dispersion. We try to check if this dispersion may also be found with chemical evolution models as an effect...
  • Publication
    Dissecting the Accretion Environments of X-ray Binaries with High Speed Coordinated Optical and X-ray Timing Observations
    We are uncovering significant optical variability in low/hard state observations of several X-ray binaries on the fastest time-scales of just tens of...
