    Using globular clusters to test gravity in the weak acceleration regime: NGC 6171
    As part of an ongoing program to test Newton’s law of gravity in the low acceleration regime using globular clusters, we present here new results obtained for...

    Using Globular Clusters to Test Newton's Law of Gravity
    New measurements of the velocity dispersion of the globular cluster ω Centauri allow us to trace its gravitational potential down to an acceleration of 8×10-9...

    Using Kepler K2 to Measure the Binary Fraction of PN Central Stars
    During the initial Kepler mission, 5 Planetary Nebula (PN) central stars were observed. The light curves for 4 of these central stars indicated a history of...

    Using Light Echoes to Map the Three-Dimensional Dust Structures Around V838 Monocerotis
    The outburst of the unusual transient V838 Monocerotis in 2002 illuminated surrounding interstellar dust, producing the most spectacular light echoes in...

    Using PNe to Explore the History of M31's Extended Disk
    The results of O/H abundances derived from PNe in M31 (accompanying poster by Hensley et al.) have extended the radius coverage of our previous gradient studies...

    Using reduction and inversion tools for THEMIS-MTR data: chromospheric reversals of a moving magnetic feature and an ephemeral region .
    New tools have been developed for THEMIS spectropolarimetric data. In this paper we present how these tools work and can be used in order to understand two...

    Using symmetries and generating functions to calculate and minimize moments of inertia
    This paper presents some formulae to calculate moments of inertia for solids of revolution and for solids generated by contour plots. For this, the symmetry...

    Using the EPOXI Mission to Measure the Dust Heterogeneity of Comet 103P/Hartley
    The Deep Impact spacecraft will fly by comet 103P/Hartley on 4 Nov 2010 with a targeted closest approach distance of 700 km providing better than 50 m/pixel...

    Using the Tremaine-Weinberg method to measure pattern speeds from Halpha velocity maps.
    The Tremaine-Weinberg method is a well-known model-independent technique for measuring density wave pattern speeds in spiral galaxies. Here we show how it can...
