    Disk Galaxies Are Self-similar: The Universality of the H I-to-Halo Mass Ratio for Isolated Disks
    Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the...

    Impacts of Bar-driven Shear and Shocks on Star Formation
    Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and...

    Kinematic measurements of gas and stars in spiral galaxies
    In this article we first give a brief historically based survey of kinematic observations, essentially of rotation curves, of spiral galaxies produced as...

    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...

    Photometric Signature of Ultraharmonic Resonances in Barred Galaxies
    Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of "dark gaps," or regions of a...

    Star Formation Histories of Ultra-faint Dwarf Galaxies: Environmental Differences between Magellanic and Non-Magellanic Satellites?
    We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2...
