    Large-amplitude Prominence Oscillations following Impact by a Coronal Jet
    Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the...

    Magnetic Fields beneath Active Region Coronal Loops
    We examine the hypothesis that multipolar magnetic fields advected by photospheric granules can contribute to heating the active chromosphere and corona. On...
