    Modeling Tidal Streams in Evolving Dark Matter Halos
    We explore whether stellar tidal streams can provide information on the secular, cosmological evolution of the Milky Way's gravitational potential and on the...

    Morphological Parameters of a Spitzer Survey of Stellar Structure in Galaxies
    The morphology of galaxies can be quantified to some degree using a set of scale-invariant parameters. Concentration (C), asymmetry (A), smoothness (S), the...

    Morphology and Dynamics of Solar Prominences from 3D MHD Simulations
    In this paper we present a numerical study of the time evolution of solar prominences embedded in sheared magnetic arcades. The prominence is represented by a...

    Morphology and Kinematics of the Gas in M51: How Interaction with NGC 5195 Has Molded the Structure of Its Arms
    The Whirlpool Galaxy is a well-studied grand design galaxy with two major spiral arms, and a large satellite NGC 5195. The arms both show long uniform sections...

    Most Hard-X-Ray-Selected Quasars in the Chandra Deep Fields are Obscured
    Measuring the population of obscured quasars is one of the key issues in understanding the evolution of active galactic nuclei (AGNs). With a redshift...

    Moving Magnetic Features as Prolongation of Penumbral Filaments
    A sequence of 633 high spatial resolution magnetograms and continuum images from SOHO MDI of NOAA AR 0330 is used to study moving magnetic feature (MMF)...

    MS 2053.7-0449: Confirmation of a Bimodal Mass Distribution from Strong Gravitational Lensing
    We present the first strong-lensing study of the mass distribution in the cluster MS 2053-04 based on HST archive data. This massive, X-ray luminous cluster has...

    Multi-layer Study of Wave Propagation in Sunspots
    We analyze the propagation of waves in sunspots from the photosphere to the chromosphere using time series of co-spatial Ca II H intensity spectra (including...
