    Survey of Ensemble Physical Properties of Cometary Nuclei
    We propose to make an albedo and radius survey of 100 cometary nuclei using IRS PU and MIPS imaging. We focus on Jupiter family comets (JFCs), which have...

    Survey of stellar associations using proper motions
    Stellar Proper Motions can be represented as great circles over the Celestial Sphere. This point of view creates a geometry over the sphere where the study of...

    Surveys for low-mass stars and brown dwarfs: Solar Neighbourhood and intermediate-age clusters Alpha Per and Collinder 359
    Lipid bilayers are key components of biomembranes; they are self-assembled two-dimensional structures, primarily serving as barriers to the leakage of cell's...

    Survival of the obscuring torus in the most powerful active galactic nuclei
    Dedicated searches suggest that the fraction of obscured Active Galactic Nuclei (AGN) decreases substantially with increasing luminosity. To explain these...
