    Survey for the Binary Progenitor in SN1006 and Update on SN1572
    We have completed a survey down to R = 15 mag of the stars within a circle of 4 arcmin radius around the nominal center of the remnant of SN 1006, one of the...

    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...

    SWIFT J052522.48+241331.8 (=1RXS J052523.2+241331) is a Cataclysmic Variable
    We report optical spectroscopy of the putative optical counterpart to the Swift source J052522.48+241331.8 (Page, Tueller & Beardmore 2007, ATEL #1279). We note...
