    Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function
    The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These...

    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...

    Infrared images and radio continuum of the H II region G 352.2+0.9.
    The component G 352.2+0.9 of the H II region/star forming complex NGC 6357 has been studied using near IR images and VLA radio continuum observations at 6 cm.
