    The Rise of Twisted Magnetic Tubes in a Stratified Medium
    First results from a two-dimensional numerical study of the buoyant rise of twisted magnetic flux tubes in the solar convection zone are presented. We show in...

    The role of active galactic nucleus feedback on the evolution of dwarf galaxies from cosmological simulations: Supermassive black holes suppress star formation in low-mass galaxies
    Aims. Recent observational studies suggest that feedback from active galactic nuclei (AGNs) may play an important role in the formation and evolution of dwarf...

    The Role of Asymmetries in Thermal Nonequilibrium
    Thermal nonequilibrium (TNE) is a fascinating situation that occurs in coronal magnetic flux tubes (loops) for which no solution to the steady-state fluid...

    The Role of Bars in AGN Fueling in Disk Galaxies Over the Last Seven Billion Years
    We present empirical constraints on the influence of stellar bars on the fueling of active galactic nuclei (AGNs) out to z = 0.84 using a sample of X-ray...

    The role of cooling induced by mixing in the mass and energy cycles of the solar atmosphere
    In many astrophysical systems, mixing between cool and hot temperature gas/plasma through Kelvin-Helmholtz-instability-driven turbulence leads to the formation...
