    The Morpho-kinematics of Planetary Nebulae with Binary Central Stars
    It is now clear that a binary formation pathway is responsible for a significant fraction of planetary nebulae, and this increased sample of known binaries...

    The Morphological and Structural Classification of Planetary Nebulae
    We present a statistical analysis of a complete sample (255) of northern planetary nebulae (PNe). Our analysis is based on morphology as a main parameter. The...

    The Most Powerful Lenses in the Universe: Quasar Microlensing as a Probe of the Lensing Galaxy
    We describe how quasar microlensing is the only way to determine the dark/stellar ratio at the interesting sub-galactic scales of several kpc and how it is the...
